This adds MBEDTLS_MD_SHA1 to the list of default hashes for TLS 1.2
handshake signatures. Although SHA-1 is weak, this option is turned on in
the default mbedtls configuration file, and allows better compatibility
with older servers. In particular it allows an stm32-mbedtls-based client
to connect to an axtls-based client (eg default unix port and esp8266).

BLE still functions correctly even though these messages are sometimes
printed by the IDF. Ignoring them allows the multi_bluetooth tests to pass
on an esp32 board.

The bit-bang implementation was replaced with the RMT implementation in
599b61c086. This commit brings back that
bit-bang code, and allows it to be selected via the new static method:
esp32.RMT.bitstream_channel(None)
The bit-bang implementation may be useful if the RMT needs to be used for
something else, or if bit-banging is more stable in certain applications.

MicroPython currently runs on core 0 of the esp32. Calling
rmt_driver_install will mean that the RMT interrupt handler is also
serviced on core 0. This can lead to glitches in the RMT output if
WiFi is enabled (for esp32.RMT and machine.bitstream).
This patch calls rmt_driver_install on core 1, ensuring that the RMT
interrupt handler is serviced on core 1. This prevents glitches.
Fixes issue #8161.

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 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.
