New boards; python3 fixes; NeoPixel power pin; UART fixes

[Note that this release is incorrectly tagged as 3.11.0 instead of v3.11.0.]

New boards:

• Fluff M0. Thanks @deshipu.

• SamE54 Xplained. Thanks @jepler.

• ndbit7 for FeatherSnow v2. Thanks @ndGarage.

• Seeduino XIA0 M0. Thanks @5kft.

• BLM Badge. Thanks @ladyada.

• QT Py. Thanks @ladyada.

• Feather M4 CAN Express. Thanks @jepler.

• Winterbloom Gemini (Castor & Pollux). Thanks @theacodes.

• Update UF2 submodule; fixe python3 compatibility. Thanks @cbc02009.

• Corrections to README.md. Thanks @dnbdmr and @dglaude.

• Fix UART support for SAMD51. Thanks @slyalfa.

• Add support for NeoPixel power indicator. Thanks @ladyada.

• SAME51 support. Thanks @jepler.

Add pewpew_m4; Improve snekboard; don't use NeoPixels when clock is wrong

Note: if you already have v3.9.0, there is no strong reason to upgrade to this release unless you're seeing spurious NeoPixel lighting when starting the user program.

• Add PewPew M4 board. Thanks @deshipu.
• Use both NeoPixels on snekboard. Thanks @keith-packard.
• Don't attempt to use NeoPixels when clock speed won't allow it. Thanks @keith-packard.

Fix SAMD51 spurious flash writes; fix SAMD21 issues

• SAMD51 Bootloader now waits until input voltage is at least 2.7V before switching to user program. This fixes an issue on power-up of infrequent writes of zeros to the first few bytes past BOOTPROT and sometimes 512 byte above that.
• SAMD21 update-bootloader-*.ino files for use with Arduino were not working. Fixed. (There is no equivalent .ino for SAMD51, but there is not a strong need, as all SAMD51 CircuitPython boards already ship with a UF2 bootloader which can be upgraded with a update-bootloader-*.uf2 file.)
• SAMD21 bootloader now repairs fuses if the first fuse is all 1's. This prevents a watchdog timer loop if the fuses have been erased.

New boards:

• 8086_commander
• uartlogger2

pybadge: correct accelerometer type; make board id numbers unique

• pybadge: correct ACCELEROMETER value
• arcade boards: assign unique values to BOOTLOADER_BOARD_ID. For Adafruit boards, use USB VID concatenated with PID.

Do NOT use the .ino files to update boards; they are broken and may brick the boards. They have been removed from this release.

pybadge, pygamer fixes; new boards; merge from upstream

• Touch up MakeCode configuration values for arcade_pybadge, arcade_pybadge_lc, and arcade_pygamer boards.
• Merge from Microsoft upstream: new boards, build additions, disable CRC for SAMD51.
• Add capablerobot_usbhub board. Also adds J-Link flashing Makefile target.
