Nfc: add basic Mifare DESFire support (#1024)
* Fix TextBox word wrap behavior
* Wrap width is 120 pixels, not 140. (140 is larger than the screen!)
* Glyph width already includes spacing; don't add 1 additional px
* When starting a new line, include wrapped glyph width in new line_width.
* Call canvas_set_font before text_box_insert_endline so that glyph
  width is calculated using correct font.
  Previous approach worked somewhat well using default TextBoxFontText but
  this version is more robust, particularly when using TextBoxFontHex.
* Add basic Mifare DESFire reading, file/app browser
* Fix build with APP_ARCHIVE=0
* Add bool type to flipper_format
* Add ability to save and load DESFire card data
* Skip over NfcSceneDeviceInfo when viewing saved DESFire info
* mf_df_clear: don't leak master key settings key versions
* When opening a DESFire card from Archive, retain UID emulation behavior
* rm unnecessary \r\n
* show Popup instead of leaving view in bad state
* Move NfcReaderRequestData out of union
  This makes it safe to emulate DESFire/EMV without clobbering card data.
* Display saved DESFire cards via NfcSceneDeviceInfo
* Display and save file metadata even when contents are missing
  This can happen when a file doesn't allow unauthenticated reads (see the
  call to mf_df_parse_read_data_response in nfc_worker.c).
