[FL-3078] Per protocol signal repeat count (#2293)

* Better Infrared protocol file structure
* Rename InfraredProtocolSpec to InfraredProtocolVariant
* Slightly better names
* Add repeat count field to protocol variant description
* Repeat the signal the appropriate number of times when brute-forcing
* Repeat the signal the appropriate number of times when sending via worker
* Better signal count logic in infrared_transmit
* Better variable names
* Convert some raw signals to messages in tv.ir
