For ports with MICROPY_VFS and MICROPY_PY_IO enabled their configuration
can now be simplified to use the defaults for mp_import_stat and
mp_builtin_open.
This commit makes no functional change, except for the following minor
points:
- the built-in "open" is removed from the minimal port (it previously did
nothing)
- the duplicate built-in "input" is removed from the esp32 port
- qemu-arm now delegates to VFS import/open

The following changes are made:
- If MICROPY_VFS is enabled then mp_vfs_import_stat and mp_vfs_open are
automatically used for mp_import_stat and mp_builtin_open respectively.
- If MICROPY_PY_IO is enabled then "open" is automatically included in the
set of builtins, and points to mp_builtin_open_obj.
This helps to clean up and simplify the most common port configuration.

Reasons for removal:
- It did not work properly because it stopped the hardware watchdog
timer while keeping the software watchdog running (issue #8597).
- There isn't a deinit method for the WDT in any other port.
- "The watchdog is not intended to be stopped. That is a feature."
(See #8600.)
This replaces occurences of
foo_t *foo = m_new_obj(foo_t);
foo->base.type = &foo_type;
with
foo_t *foo = mp_obj_malloc(foo_t, &foo_type);
Excludes any places where base is a sub-field or when new0/memset is used.

The main functionality of this info function is available via the existing
micropython.mem_info() and micropython.qstr_info() functions. The printing
of the address space layout doesn't add much and removing esp.info() saves
about 600 bytes.

The inclusion of `umachine` in the list of built-in modules is now done
centrally in py/objmodule.c. Enabling MICROPY_PY_MACHINE will include this
module.
As part of this, all ports now have `umachine` as the core module name
(previously some had only `machine` as the name).

These removed ones are either unused by MicroPython or provided by osapi.h
in the SDK. In particular ets_delay_us() has different signatures for
different versions of the SDK, so best to let it provide the declaration.
Fixes issue #8095.

If MICROPY_PY_SYS_PATH_ARGV_DEFAULTS is enabled (which it is by default)
then sys.path and sys.argv will be initialised and populated with default
values. This keeps all bare-metal ports aligned.

Frozen modules will be searched preferentially, but gives the user the
ability to override this behavior.
This matches the previous behavior where "" was implicitly the frozen
search path, but the frozen list was checked before the filesystem.

This will be used by https://micropython.org/download/ to generate the
full listing of boards and firmware files.
Optionally supports a board.md for additional customisation of the

This commit refactors machine.PWM and creates extmod/machine_pwm.c. The
esp8266, esp32 and rp2 ports all use this and provide implementations of
the required PWM functionality. This helps to reduce code duplication and
keep the same Python API across ports.
This commit does not make any functional changes.

The zephyr port doesn't support SoftI2C so it's not enabled, and the legacy
I2C constructor check can be removed.

This moves mp_pending_exception from mp_state_vm_t to mp_state_thread_t.
This allows exceptions to be scheduled on a specific thread.

Commit 0abf6f830c removed _boot.py from the
manifest for the GENERIC_512K board because the build does not include a
filesystem. But the main code expects _boot.py to be there and prints an
error if it's not. So add a custom _boot.py, which just sets the
gc.threshold().

The 512k build does not have a filesystem so there is no reason to include
the filesystem-related modules. This commit provides a custom manifest.py
for this board which no longer includes: _boot.py, flashbdev.py,
inisetup.py, upip.py, upip_utarfile.py. This cuts the build down by about
9k of flash.

This helper is added to properly set a pending exception, to mirror
mp_sched_schedule(), which schedules a function.

If MICROPY_ENABLE_SCHEDULER is enabled then MP_STATE_VM(sched_state) must
be updated after handling the pending exception, which is done by the
mp_handle_pending() function.

With a warning that this way of constructing software I2C/SPI is
deprecated. The check and warning will be removed in a future release.
This should help existing code to migrate to the new SoftI2C/SoftSPI types.
