Test driver for joypad inputs

Add a new joypad input driver:
- hide driver behind #ifdef and enable it in config_params.sh
- add a new config parameter to specify the test input file
- add aux files: additional config files that cancel out any binds
  that may be present in RA config, autoconfig profile for
  test joypads, test input file that matches controller test
  sequence
