[FL-3832] Use static synchronisation primitives (#3679)
* Use static mutex
* Add static_assert checks
* Use static semaphore
* Fix formatting
* Use static stream buffer
* Use static timer
* Use static event group
* Increase allocation size for stream buffer
* Remove recursive bit from the mutex before freeing
* Prevent service tasks from ever returning
* Use static threads
* Do not realloc memory when changing stack size
* Use FuriSemaphore instead of raw FreeRTOS one in rpc_test
* Remove redundant includes
* Abolish FreeRTOS dynamic allocation
* Improve FuriMutex
* Improve FuriMessageQueue
* Remove redundant comments and parentheses
* Clean up code more
* Create service threads via a dedicated constructor
* Minor code improvements
* Update docs for FuriThread, FuriTimer
* Fix doxygen typo
* Use a bigger buffer for static StreamBuffer
* Furi: remove timer control block only when timer thread have completed all operations
