Furi: A Lot of Fixes (#3942)

- BT Service: cleanup code
- Dialog: correct release order in file browser
- Rpc: rollback to pre #3881 state
- Kernel: fix inverted behavior in furi_kernel_is_running
- Log: properly take mutex when kernel is not running
- Thread: rework tread control block scrubbing procedure, ensure that we don't do stupid things in idle task, add new priority for init task
- Timer: add control queue flush method, force flush on stop
- Furi: system init task now performs thread scrubbing
- BleGlue: add some extra checks
- FreeRTOSConfig: fix bunch of issues that were preventing configuration from being properly applied and cleanup
