2025q1 release

This release covers everything from 2025-01-01 and has been tested with avr-gcc
v13.2.0 from upstream and arm-none-eabi-gcc v13.2.1 from xpack.

Features:

• Add missing HSI48-related functionality for some STM32.
• Enable Cortex-M7 I/D-Cache via lbuild.
• Speed up startup copying and zeroing of data sections.

Fixes:

• Fix wrong CMake program target *.elf path.

Known bugs:

• STM32F723 is missing support to use built-in USB HS PHY. See #1171.
• OpenOCD cannot enable SWO on STM32H7 targets. See #1079.
• arm-none-eabi-gdb TUI and GDBGUI interfaces are not supported on Windows.
  See #591.
• Generating modm on Windows creates paths with \ that are not compatible with
  Unix. See #310.

  when the configuration changes. See #285.
