Furi: core refactoring and CMSIS removal part 2 (#1410)
* Furi: rename and move core
* Furi: drop CMSIS_OS header and unused api, partially refactor and cleanup the rest
* Furi: CMSIS_OS drop and refactoring.
* Furi: refactoring, remove cmsis legacy
* Furi: fix incorrect assert on queue deallocation, cleanup timer
* Furi: improve delay api, get rid of floats
* hal: dropped furi_hal_crc
* Furi: move DWT based delay to cortex HAL
* Furi: update core documentation
