Furi: cleanup crash use (#3175) 
* Furi: optional message in furi_crash and furi_halt
* Consistent furi_crash use
* UnitTests: crash instead of assert
* furi: check: fixed macro for default arg
* unit_tests: fixed crashes everywhere
* lib: infrared: fixed PVS warnings
* furi: eliminated __FURI_ASSERT_MESSAGE_FLAG
* Furi: update check.h docs
* Furi: add check.h usage note
* Docs: grammar
