CCID: Improve request and response data handling (#3741)
* CCID: Improve request and response data handling
  - Add iso7816_set_response function: serves a helpers to set SW1 and SW2 values
  - improved iso7816_read_response_apdu by correctly parsing Lc and Le values
  - add client script to make testing easier
* lint and rename
* Format
* Review changes: pragma once, typedef
* Move command/response data and datalen into respective structures
* Remove conditional for Lc=0
* Fix comment: Le
* Make PVS happy and fix spelling
