2023q4 release

This release covers everything from 2023-10-01 and has been tested with avr-gcc
v12.2.0 from Upstream and arm-none-eabi-gcc v12.2.1 from xpack.

Features:

• STM32H7 SPI driver with DMA support.

Integrated Projects:

• ETL upgraded to v20.38.10.
• LVGL upgraded to v8.3.11.
• Nanopb upgraded to v0.4.8.
• STM32G0 headers upgraded to v1.4.3.
• STM32F4 headers upgraded to v2.6.9.
• STM32U5 headers upgraded to v1.3.1.

Fixes:

• Fix SPI clocks on Nucleo-H723ZG boards.
• Do not require protothreads to use SPI with fibers.
• Place main stack in DMA-able SRAM on STM32H7.

New device drivers:

• BMI088 IMU driver as modm:driver:bmi088.

Known bugs:

• Fibers are not implemented for ARM64 targets. See #1111.
• OpenOCD cannot enable SWO on STM32H7 targets. See #1079.
• STM32F7: D-Cache not enabled by default. See #485.
• lbuild build and lbuild clean do not remove all previously generated files
  when the configuration changes. See #285.
• Generating modm on Windows creates paths with \ that are not compatible with
  Unix. See #310.
• arm-none-eabi-gdb TUI and GDBGUI interfaces are not supported on Windows.
  See #591.
