JSON schema files for test input driver and netretropad

[zoltanvb]

Description

JSON schema files for input test driver and the Remote Retropad check side.

I did not find any straightforward method to indicate numeric constants here in the schema, such as:

RetroArch/input/drivers_joypad/test_joypad.c

Line 46 in fee6ac3

#define JOYPAD_TEST_COMMAND_ADD_CONTROLLER 1

for actions, or:

RetroArch/libretro-common/include/libretro.h

Line 317 in fee6ac3

#define RETRO_DEVICE_ID_JOYPAD_B 0

for expected_button, without having to change the processing side, which I would not like to do, so writing test inputs will still be a bit inconvenient.

Schemas can be applied without error:

jsonschema test_input_driver_schema.json  -i test_input_joypad.ratst
jsonschema netretropad_input_check_schema.json -i netretropad_all_inputs.ratst

Whoops, I didn't notice this until just now. Sorry about that.

At any rate, looks good to me. Thank you!
