SubGhz: sending / receiving messages via subghz (#851)

Browse Source 
* SubGhz: add worker subghz_txrx
* SubGhz: added support for transferring Russian characters and support for backspace in CLI subghz_txrx
* SubGhz: refactoring subghz_txrx_worker, added a callback for accepting data in an empty one RX buffer
* SubGhz: fix conflict
* SubGhz: fix syntax errors
* Cli: document string_move usage and its behavior
* FuriHal: update subghz api and documentation. Subghz: move chat to subghz cli subcommand.
* Subghz: update text in chat cli
