[FL-2198], [FL-2161] NFC emulation refactoring (#968)

* rfal: add state changed callback
* furi_hal_nfc: add NFC-A emulation API
* nfc: add emulation logger, refactor scenes
* elements: fix text_box element
* gui: fix text box module
* nfc: remove unnecessary buffers
* nfc: introduce emulation callback concept
* nfc: format sources
* bt settings: fix incorrect scene switch
* bt settings: format sources
* Debug: fix x2d import for python 3
* Gui: rename method name widget_clear to widget_reset
* nfc: add nfca emulation handler
* nfc: add global custom events enum
* nfc: UID emulation Data -> Log
* furi_hal_nfc: fix incorrect timings
* u2f, badusb: widget_clear() -> widget_reset()
