Added -Wundef to compiler options (#3815)

* fbt: added -Wundef to compiler options; libs: various small fixes for missing defines; desktop: proper access to current RTOS config
* apps: fixes for FURI_DEBUG handling
* rpc: unified definition checks
* Cleanup various defines use
* Cleanup configs and move SVCall ISR priority configuration to furi_hal_interrupts
