This diff adds an initial version of the highlighter shape. At this
stage, it's a complete copy of the draw tool minus the following
features:
* Fills
* Stroke types
* Closed shapes
I've created a new shape util (a copy-paste of the draw one with stuff
renamed/deleted) but reused the state chart nodes for the draw shape.
Currently this new tool looks exactly like the draw tool, but that'll be
changing soon!
The UI here is extremely WIP. The highlighter tool is behind a feature
flag, but once enabled is accessible through the tool bar. There's a
first-draft highlighter icon (i didn't spend much time on this, it's not
super legible on non-retina displays yet imo), and the tool is bound to
the `i` key (any better suggestions? `h` is taken by the hand tool)
### The plan
1. initial highlighter shape/tool #1401 **>you are here<**
2. sandwich rendering for highlighter shapes #1418
3. shape styling - new colours and sizes, lightweight perfect freehand
changes

### Change Type
- [x] `minor` — New Feature
### Test Plan
1. Select the laser pointer tool
2. Draw some lasers.
### Release Notes
- Adds the laser pointer tool.
Keyboard shortcuts for selecting tools still worked in readonly mode.
This now disables them - except for select, hand, and zoom tool.
### Change Type
- [x] `patch` — Bug Fix
### Test Plan
1. Create a readonly room.
2. Press keyboard shortcuts for tools and make sure we don't transition
to them (tools toolbar should always show either select or hand tool as
active).
3. Also make sure the keyboard shortcuts still work in non readonly
rooms.
- [ ] Unit Tests
- [ ] Webdriver tests
### Release Notes
- Disable keyboard shortcut events for tools in readonly mode. We only
allow the select, hand tools, and zoom tool.
