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.

WeAct Studio RP2040
The WeAct Studio RP2040 Board is based on the Raspberry Pi RP2040 and can be purchased with 2/4/8/16 MiB of flash.
These boards are available from a number of resellers and often have the name "Pico Board RP2040". WeAct maintain the WeActStudio.RP2040CoreBoard repository containing information on the board.
Build notes
Builds can be configured with the BOARD_VARIANT parameter. Valid variants
can be displayed with the query-variant target. An example:
> cd ports/rp2
> make BOARD=WEACTSTUDIO query-variants
VARIANTS: flash_2mb flash_4mb flash_8mb flash_16mb
> make BOARD=WEACTSTUDIO BOARD_VARIANT=flash_8mb submodules all # Build the 8 MiB variant
flash_16mb is the default if BOARD_VARIANT is not supplied.
Board-specific modules
The board module contains definitions for the onboard LED and user button.
Example:
> import board
> board.led.toggle() # Toggles the state of the on-board LED
> board.key.value() # Returns 0 or 1 corresponding to the state of the user key
