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.
