This provides a way to enable features and changes slated for MicroPython
2.x, by running `make MICROPY_PREVIEW_VERSION_2=1`. Also supported for
the cmake ports (except Zephyr).
This is an alternative to having a 2.x development branch (or equivalently,
keeping a 1.x release branch). Any feature or change that needs to be
"hidden" until 2.x can use this flag (either in the Makefile or the
preprocessor).
A good example is changing function arguments or other public API features,
in particular to aid in improving consistency between ports.
When `MICROPY_PREVIEW_VERSION_2` is enabled, the REPL banner is amended to
say "MicroPython (with v2.0 preview) vX.Y.Z", and sys.implementation gets a
new field `_v2` set to `True`.

PICO might not always be a unique name across all ports, and the
convention generally for other boards is to do VENDOR_BOARD.

This allows switching between variants without clobbering the build
output.

This is difficult to implement on cmake-based ports, and having the list
of variants in mpconfigboard.{cmake,mk} duplicates information that's
already in board.json.
This removes the existing query-variants make target from stm32 & rp2
and the definition of BOARD_VARIANTS from the various board files.
Also renames the cmake variable to MICROPY_BOARD_VARIANT to match other
variables such as MICROPY_BOARD. The make variable stays as
BOARD_VARIANT.

This matches the behavior of the makefile ports but implemented for CMake,
making it easy to specify custom board definitions.

Used to be special-cased for Pico, but now everything depends on
micropython-lib if it's using a frozen manifest.

This includes:
- Configuration file for the cyw43-driver.
- Integration of cyw43-driver into the build, using lwIP.
- Enhancements to machine.Pin to support extension IO pins provided by the
CYW43xx.
- More mp-hal pin helper functions.
- mp_hal_get_mac_ascii MAC address helper function.
- Addition of rp2.country() function to set the country code.
A board can enable this driver by setting MICROPY_PY_NETWORK_CYW43 in their
cmake snippet.

This change allows to build firmware for different rp2-based boards,
following how it is done in other ports like stm32 and esp32. So far only
the original Pico and Adafruit Feather RP2040 are added. Board names
should match (sans case) those in pico-sdk/src/boards/include/boards/.
Usage: Pico firmware can be build either using make as previously (it is
the default board) or by `make BOARD=PICO`. Feather is built by `make
BOARD=ADAFRUIT_FEATHER_RP2040`. Only the board name and flash drive size
is set, pin definition is taken from the appropriate pico-sdk board
definition. Firmware is saved in the directory build-BOARD_NAME.
The parts that are generic are added to py/ so they can be used by other
ports that use CMake.
py/usermod.cmake:
* Creates a usermod target to hang user C/CXX modules from.
* Gathers sources from user C/CXX modules and libs for QSTR scan.
ports/rp2/CMakeLists.txt:
* Includes py/usermod.cmake.
* Links the resulting usermod library to the MicroPython target.
py/mkrules.cmake:
Add cxxflags to qstr.i.last custom command for CXX modules:
* MICROPY_CPP_FLAGS so CXX modules will find includes.
* -DNO_QSTR to fix fatal error missing "genhdr/qstrdefs.generated.h".
Usage:
The rp2 port can be linked against user C modules by running:
make USER_C_MODULES=/path/to/module/micropython.cmake
CMake will print a list of included modules.

This commit adds a new port "rp2" which targets the new Raspberry Pi RP2040
microcontroller.
The build system uses pure cmake (with a small Makefile wrapper for
convenience). The USB driver is TinyUSB, and there is a machine module
with most of the standard classes implemented. Some examples are provided
in the examples/rp2/ directory.
