[PATCH] Documentation: subsystem-apis: Categorize remaining subsystems

[Costa Shulyupin]

There is a FIXME that says to organize subsystems listed in
subsystem-apis.rst. Fulfill it by categorize remaining subsytems
by purpose/themes, while sorting entries in each category.

HID devices are already categorized in 3c591cc954d56e ("docs:
consolidate human interface subsystems").
