The main Makefile builds the mpy-cross executable automatically if
it doesn't exist since 78718fffb1,
so build it first to make sure it doesn't get needlessly rebuilt.
This board has only 2MiB of flash so the build needs to be reduced in size
to fit. Commit 549448e8bb made all boards
build with -O2 by default (for performance) so this overrides that default.

This is needed because these ports allocate mbedtls data on the MicroPython
heap, and SSL socket objects must be fully cleaned up when they are garbage
collected, to free this memory allocated by mbedtls. As part of this,
gc_sweep_all() will now ensure that the MP_STATE_PORT(mbedtls_memory)
linked-list is fully deallocated on soft reset.

CONFIG_USB was removed in Zephyr v2.7.0 after some Kconfig rework that
made it sufficient to use CONFIG_USB_DEVICE_STACK only.

Updates the Zephyr port to get the UART console device from devicetree
instead of Kconfig. The Kconfig option CONFIG_UART_CONSOLE_ON_DEV_NAME
was removed in Zephyr v2.7.0.

The reboot header was moved to a different path in Zephyr v2.6.0. The
old path was deprecated for two releases (v2.6.0 and v2.7.0) and will no
longer be supported after Zephyr v2.7.0.

As a prerequisite to upgrading to Zephyr v2.7.0, upgrade the minimum
CMake version required for the Zephyr port to 3.20.0.

As a prerequisite to upgrading to Zephyr v2.7.0, upgrade CI to use
Zephyr docker image v0.21.0. In particular, this is needed to pick up a
newer CMake version because Zephyr v2.7.0 increased the minimum CMake
version required to 3.20.0.

After changing the bitstream implementation to use the RMT driver in
commit 72d86158121e32bbabaeade08f449d507bf40f9a
("esp32/machine_bitstream.c: Replace with RMT-based driver."), using
multiple `Neopixel` instances shows signal duplication between the
instances (i.e. a `write()` on one instance is written to all instances).
On invocation, the rmt driver configures the GPIO matrix to route the
output signal to the respective GPIO pin. When called for a different
`NeoPixel` instance using a different pin, the new route is established,
but the old route still exists. Now, the RMT output signal is sent to both
pins.
Fix this by setting the standard GPIO output function for the current pin
after uninstalling the RMT driver.

The qstr_last_chunk is not collected by the garbage collector. This relies
on the assertion that qstr_pool_t also references the qstr_last_chunk. If
an exception is raised while allocating the qstr_pool_t, qstr_last_chunk
has to be invalidated not to become a dangling reference at the next
garbage collection.

And how they relate to MicroPython. As these features are implemented (or
the decision is made to not implement them) the tables can be updated to
document the differences between MicroPython and standard Python.
In commit 86ce442607 the '.frozen' entry was
added at the start of sys.path, to allow control over when frozen modules
are searched during import, and retain existing behaviour whereby frozen
was searched before the filesystem.
But Python semantics of sys.path require sys.path[0] to be the directory of
the currently executing script, or ''.
This commit moves the '.frozen' entry to second place in sys.path, so
sys.path[0] retains its correct value (described above).
