[FL-1528] SubGhz: dma send (#579)
* Gui: input injection in screen stream * Cli: expose ASCII table in public header * SubGhz: dma output draft * SubGhz: output initialization cleanup * SubGhz: update dma send routine, add subghz_tx cli command. * SubGhz: proper register address for DMA * SubGhz: proper, fully working dma+tim2 configuration * SubGhz: transmit PT with cli. * Drivers: fix invalid size in CC1101 PA_TABLE loading routine. * Interrupts: configurable DMA isrs. * F5: backport fixes. * SubGhz: free buffer after use * SubGhz: use sleep instead of reset at the end * SubGhz: async tx repeat with circular DMA * SubGhz: disable dma channel on complete, adjust PT send timings * SubGhz: backport function singature change to F5 * SubGhz: add tx debug gpio
