[FL-2591] Furi: remove CMSIS thread api, migrate to FuriThread, remove unused CMSIS APIs (#1333)
* Furi: remove CMSIS thread api, migrate to FuriThread, remove unused CMSIS APIs
* Furi: magic thread catcher validating thread completion; backtrace improver
* Furi: allow furi_thread_get_current_id outside of thread context
* Furi: use IRQ instead of ISR for core primitives
