Sleeping in sysworkq is a very bad idea, it can trash any hope of
realtimeness at best, deadlock the whole system at worse.
Add a check to input_report to downgrade the event to K_NO_WAIT
automatically when called from the sysworkq, similarly to what's done by
other APIs (netbuf and bluetooth), though only log if messages are
actually dropped.

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.

Rename the internal input callback structure to input_callback. This is
for coherency with "INPUT_CALLBACK_DEFINE" and other similar code paths
in Zephyr, and also to avoid confusion with terminology.
This is an internal structure, applications should not have any
references to it so there should be no need for any release note
entries.

Until now iterable sections APIs have been part of the toolchain
(common) headers. They are not strictly related to a toolchain, they
just rely on linker providing support for sections. Most files relied on
indirect includes to access the API, now, it is included as needed.

Initial commit introducing the input subsystem into Zephyr.
Includes the input_event data structure, the input_report_* APIs, an
iterables sections based subscription API and two operation modes:
synchronous, where the listeners are called directly, and asynchronous,
where the listeners are called in a dedicated thread.
