[FL-2955], [FL-2953] SubGhz: fix RAW "Send never ends" (#1979)

Browse Source 
* SubGhz: fix RAW "Send never ends"
* SubGhz: delete comments
* SubGhz: RAW file parsing speed increase
* SubGhz: fix level_duration_is_wait
* SubGhz: modification furi_hal_subghz_async_tx_refill
* SubGhz: furi_hal_subghz_stop_async_rx
* SubGhz: hal unit test and better async tx yield handling
* FuriHal: proper async tx end in subghz, vibro on power off
* FuriHal: variable naming in subghz
* SubGhz,FuriHal: extreme timings in subghz hal unit tests, remove memset in async tx buffer fill routine
* FuriHal: small refinements in subghz
