This PR changes the way `Store.squashHistoryEntries` works. Previously,
the function would iterate through every entry and squash it against the
current entry (using `squashRecordDiffs`) to get the new current entry.
However, `squashRecordDiffs` does basically the same pattern, iterating
through the properties of every diff. As a result, each diff would be
iterated through twice: once as itself, and once again in the next
current.
This PR tweaks the function to operate on as many diffs as possible at
once.

### Release Notes
- Minor improvement when modifying multiple shapes at once.
This PR does a few things to help with performance:
1. Instead of doing changes on raf we now do them 60 times per second.
This limits the number of updates on high refresh rate screens like the
iPad. With the current code this only applied to the history updates (so
when you subscribed to the updates), but the next point takes this a bit
futher.
2. We now trigger react updates 60 times per second. This is a change in
`useValue` and `useStateTracking` hooks.
3. We now throttle the inputs (like the `pointerMove`) in state nodes.
This means we batch multiple inputs and only apply them at most 60 times
per second.
We had to adjust our own tests to pass after this change so I marked
this as major as it might require the users of the library to do the
same.
Few observations:
- The browser calls the raf callbacks when it can. If it gets
overwhelmed it will call them further and further apart. As things call
down it will start calling them more frequently again. You can clearly
see this in the drawing example. When fps gets to a certain level we
start to get fewer updates, then fps can recover a bit. This makes the
experience quite janky. The updates can be kinda ok one second (dropping
frames, but consistently) and then they can completely stop and you have
to let go of the mouse to make them happen again. With the new logic it
seems everything is a lot more consistent.
- We might look into variable refresh rates to prevent this overtaxing
of the browser. Like when we see that the times between our updates are
getting higher we could make the updates less frequent. If we then see
that they are happening more often we could ramp them back up. I had an
[experiment for this
here](4834863966 (diff-318e71563d7c47173f89ec084ca44417cf70fc72faac85b96f48b856a8aec466L30-L35)).
Few tests below. Used 6x slowdown for these.

# Drawing
Comparison is not 100% fair, we don't store the intermediate inputs
right now. That said, tick should still only produce once update so I do
think we can get a sense of the differences.

This PR adds a validation mode whereby previous known-to-be-valid values
can be used to speed up the validation process itself. At the same time
it enables us to do fine-grained equality checking on records much more
quickly than by using something like lodash isEqual, and using that we
can prevent triggering effects for record updates that don't actually
alter any values in the store.
Here's some preliminary perf testing of average time spent in
`store.put()` during some common interactions
| task | before (ms) | after (ms) |
| ---- | ---- | ---- |
| drawing lines | 0.0403 | 0.0214 |
| drawing boxes | 0.0408 | 0.0348 |
| translating lines | 0.0352 | 0.0042 |
| translating boxes | 0.0051 | 0.0032 |
| rotating lines | 0.0312 | 0.0065 |
| rotating boxes | 0.0053 | 0.0035 |
| brush selecting boxes | 0.0200 | 0.0232 |
| traversal with shapes | 0.0130 | 0.0108 |
| traversal without shapes | 0.0201 | 0.0173 |
**traversal** means moving the camera and pointer around the canvas
#### Discussion
At the scale of hundredths of a millisecond these .put operations are so
fast that even if they became literally instantaneous the change would
not be human perceptible. That said, there is an overall marked
improvement here. Especially for dealing with draw shapes.
These figures are also mostly in line with expectations, aside from a
couple of things:
- I don't understand why the `brush selecting boxes` task got slower
after the change.
- I don't understand why the `traversal` tasks are slower than the
`translating boxes` task, both before and after. I would expect that
.putting shape records would be much slower than .putting pointer/camera
records (since the latter have fewer and simpler properties)

This prevents geometry from being recalculated when dragging shapes
around. It uses an equality check on the shape props to opt out of
recalculations. This still allows bounds to be calculated based on other
reactive values, so if folks really want to use x,y values or opacity or
whatever, they can call editor.getShape(id) when making their
calculation.

Use the app! Especially undo and redo. Our tests are passing but I've
found more cases where our coverage fails to catch issues.
### Release Notes

This PR improves the types for the Store.
- renames `StoreSnapshot` to `SerializedStore`, which is the return type
of `Store.serialize`
- creates `StoreSnapshot` as a type for the return type of
`Store.getSnapshot` / the argument type for `Store.loadSnapshot`
- creates `TLStoreSnapshot` as the type used for the `TLStore`.
This came out of a session I had with a user. This should prevent
needing to import types from `@tldraw/store` directly.
### Change Type

### Test Plan

### Release Notes
- [dev] Rename `StoreSnapshot` to `SerializedStore`
- [dev] Create new `StoreSnapshot` as type related to
`getSnapshot`/`loadSnapshot`
It tried to get out but we're dragging it back in.
This PR brings [signia](https://github.com/tldraw/signia) back into
tldraw as @tldraw/state.

This PR
- Removes UserDocumentRecordType
- moving isSnapMode to user preferences
- moving isGridMode and isPenMode to InstanceRecordType
- deleting the other properties which are no longer needed.
- Creates a separate pipeline for persisting instance state.
Previously the instance state records were stored alongside the document
state records, and in order to load the state for a particular instance
(in our case, a particular tab) you needed to pass the 'instanceId'
prop. This prop ended up totally pervading the public API and people ran
into all kinds of issues with it, e.g. using the same instance id in
multiple editor instances.
There was also an issue whereby it was hard for us to clean up old
instance state so the idb table ended up bloating over time.
This PR makes it so that rather than passing an instanceId, you load the
instance state yourself while creating the store. It provides tools to
make that easy.
- Undoes the assumption that we might have more than one instance's
state in the store.
- Like `document`, `instance` now has a singleton id
`instance:instance`.
- Page state ids and camera ids are no longer random, but rather derive
from the page they belong to. This is like having a foreign primary key
in SQL databases. It's something i'd love to support fully as part of
the RecordType/Store api.
Tests to do
- [x] Test Migrations
- [x] Test Store.listen filtering
- [x] Make type sets in Store public and readonly
- [x] Test RecordType.createId
- [x] Test Instance state snapshot loading/exporting
- [x] Manual test File I/O
- [x] Manual test Vscode extension with multiple tabs
- [x] Audit usages of store.query
- [x] Audit usages of changed types: InstanceRecordType, 'instance',
InstancePageStateRecordType, 'instance_page_state', 'user_document',
'camera', CameraRecordType, InstancePresenceRecordType,
'instance_presence'
- [x] Test user preferences
- [x] Manual test isSnapMode and isGridMode and isPenMode
- [ ] Test indexedDb functions
- [x] Add instanceId stuff back

This PR cleans up the file names and imports for @tldraw/tlschema.
It also:

### Release Notes
- [editor] Remove `app.createShapeId`

This PR renames the `@tldraw/tlstore` package to `@tldraw/store`, mainly
to avoid confusion between `TLStore`. Will be doing the same with other
packages.
