CCID: App changes (#3837)
- Keep ccid_callback and buffer as private to the iso7816_handler
- set usb ccid callback from iso7816_handler (to ensure the right structure is being passed)
- make iso7816 related code independent from furi related code (goal is to make it independently testable)
- rename vars
