[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

* SIRC20 | 7b LSB | 13b LSB |

* No way to determine either next message is repeat or not,
* so recognize only fact message received. Sony remotes always send at least 3 messages.
* Assume 8 last extended bits for SIRC20 are address bits.
