Use an explicit callback name so that multiple instances of this do not
result in a:
redefinition of '_input_callback__longpress_cb'
error. This used to work when it was using unique generated wrappers,
but now it needs an index in the callback name.
Use it in one of the API tests as well, just in case.

Add a void *user_data pointer to the input callback structure. This is
useful for driver to get back the driver data structure and avoid
defining wrapper functions.

Looking back at the current INPUT_LISTENER_CB_DEFINE api naming, it
feels like it's a bit overloaded. Rename it to a simpler
INPUT_CALLBACK_DEFINE.

Add some initial tests for the input subsystem, covering all the APIs in
both synchronous and thread mode.
