[FL-3640] NFC: Felica UID emulation (#3190)

* Added basic template of Felica listener
* Raw nfc felica listener functions
* Added functions to setup chip for felica listener
* Cleanup function templates from unnecessary parts
* Removed todo comment
* Updated api versions
* Adjusted chip config for felica
* Set proper chip passive target mode for felica
* Added felica function to unit tests
* Update furi_hal_nfc_felica.c
* Removed duplication
