[FL-2399, FL-2261] Tickless sleep shenanigans (#1168)

Browse Source 
* Disable USART in sleep
* Restore UART state on suspend/resume
* FuriHal: Enable stop mode and add insomnia to I2C and SPI
* Remove IDLE interrupt
* FuriHal: add FPU isr and disable all FPU interrupt, add core2 stop mode configuration on deep sleep
* FuriHal: tie stop mode debug with debug rtc flag
* FuriHal: adjust flash latency on clock switch, tie mcu debug with RTC debug flag
* FuriHal: move resource init to early stage
* Add EXTI pending check, enable debug traps with compile-time flag
* Wrap sleep debug functions in conditional compilation
* Remove erroneous changed
* Do not use CSS, remove it from everywhere
* Enable/disable USB on VBUS connect (prototype)
* FuriHal: add LPMS and DEEPSLEEP magic, workaround state inconsistency between cores
* FuriHal: honor c1 LMPS
* USB mode switch fix
* Applications: add flags and insomnia bypass system
* Correct spelling
* FuriHal: cleanup insomnia usage, reset sleep flags on wakeup, add shutdown api
* FuriHal: extra check on reinit request
* FuriHal: rename gpio_display_rst pin to gpio_display_rst_n
* FuriHal: add debug HAL
* FuriHal: add some magic to core2 reload procedure, fix issue with crash on ble keyboard exit
* FuriHal: cleanup ble glue, add BLE_GLUE_DEBUG flag
* FuriHal: ble reinit API, move os timer to LPTIM1 for deep sleep capability, shutdown that works
* FuriHal: take insomnia while shutdown
* Remove USB switch on/off on VBUS change
* Better tick skew handling
* Improve tick consistency under load
* Add USB_HP dummy IRQ handler
* Move interrupt check closer to sleep
* Clean up includes
* Re-enable Insomnia globally
* FuriHal: enable CSS
* FuriHal: remove questionable core2 clock shenanigans
* FuriHal: use core1 RCC registers in idle timer config
* FuriHal: return back CSS handlers, add lptim isr dispatching
