cli: --input: add support for evdev inputs

This adds support for evdev inputs which were introduced in 7.4.0,
as well as passthrough inputs and some other misc options to complete
the --input command.

New suboptions:
* source.evdev
* source.dev
* source.repeat
* source.grab
* source.grabToggle
* model
