[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
