Makefile support for 32-bit Archim board and new TMC library (#11997)

* Support new TMC library and 32-bit Archim board

- Added IS_MCU flag
  - When IS_MCU flag is 1, AVR compiler will be used
  - When IS_MCU flag is 0, ARM compiler will be used
- Added support for new TMC library
- Added support for a 32-bit Archim board, which could probably be used as a basis for other 32-bit boards.
