Submodule on the fly

[hathach]

Describe the PR

• Simplify mcu driver submodule by fetch needed one when running make. User does not need to --init all or manual fetch one. Save time for CI as well
• Use submodule lib/FreeRTOS-Kernel instead of the chunky lib/FreeRTOS
• Remove submodule lib/CMSIS_4 (300MB) since no MCUs use it (nrf is updated to CMSIS_5)
• Remove submodule lib/CMSIS_5 (160MB) , add local copy release to save bandwidth
• Update microchip_driver to not include submodule asf5, making it simply to init (without recusrive flag)
• Move msp430 and fomu to its own family to optimize ci build
