[FL-2219, FL-2251] System, FuriCore, FuriHal: various bug fixes and improvements (#986)

* Replace irq shenanigans with critical section
* Power: halt system on power off instead of crash.
* Gui: properly handle input event on NULL current_view
* FuriHal: correct gpio configuration sequence
* FuriHal: cleanup uart initialization. Makefile: allow to disable thread support.
* Loader: improve locking, fix simultaneous app start crash, full command line args support for gui apps, more consistent insomnia
* Loader: correct spelling
* FuriHal: increase gpio configuration readability
* FuriHal: correct gpio configuration error when mode is GpioModeEventRiseFall
