Test input joypad driver (#16370) 
* 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

* Fixes and comments for test input driver.

/*
* To-do:
* - Some sort of connection control, it only sends packets
* but there is no acknoledgement of a connection o keepalives
* - Send player name
* - Render something on-screen maybe a gui to configure IP and port
instead of the ridiculously long strings we're using now
* - Allow changing IP address and port in runtime
* - Input recording / Combos
* - Enable test input loading from menu
* - Visualization of keyboard and aux inputs (gyro, accelero, light)
