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 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).

This allows the remote MicroPython instance to create and delete
directories from the mounted host filesystem in addition to the already
existing functionality of reading, creating, and modifying files.

Save and restore the same duty cycle when the frequency (or frequency
resolution) is changed. This allows a smooth frequency change.
Also update the esp32 PWM quickref to be clearer.
This commit makes sure that the value zero is always encoded in an mpz_t as
neg=0 and len=0 (previously it was just len=0).
This invariant is needed for some of the bitwise operations that operate on
negative numbers, because they cannot handle -0. For example
(-((1<<100)-(1<<100)))|1 was being computed as -65535, instead of 1.
Fixes issue #8042.

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.

The mp_sys_path_obj and mp_sys_argv_obj objects are only used by the
runtime and accessible from Python if MICROPY_PY_SYS is enabled. So
exclude them from the runtime state if this option is disabled.

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 changes makemanifest.py & mpy-tool.py to merge string and mpy names
into the same list (now mp_frozen_names).
The various paths for loading a frozen module (mp_find_frozen_module) and
checking existence of a frozen module (mp_frozen_stat) use a common
function that searches this list.
In addition, the frozen lookup will now only take place if the path starts
with ".frozen", which needs to be added to sys.path.
This fixes issues #1804, #2322, #3509, #6419.

This feature is not enabled on any port, it's not in CPython's io module,
and functionality is better suited to the micropython-lib implementation of
pkg_resources.
Default SPI pins are now correctly assigned by machine_hw_spi.c even for S2
and S3. mpconfigboard.h files define defaults with flipped SPI(1) and
SPI(2) to workaround a bug in machine_hw_spi.c - the bug is fixed.

Use IO_MUX pins as defined by ESP IDF in soc/esp32/include/soc/spi_pins.h
ESP32S2 and S3 don't have IO_MUX pins for SPI3, GPIO matrix is always used.
Choose suitable defaults for S2 and S3.
ESP32C3 does not have SPI3 at all. Don't define pin mappings for it.
