service: placeholder handlers for known but unimplemented commands

Add StubReplyZeroed, StubReplyEvent and StubReplyInterface to
ServiceFrameworkBase: for Switch 2 callers they reply with zeroed data, with
zeroed data and a copy handle to an event that never fires, or with an nx2:
stub interface; other callers get the unimplemented-function path as before.
Each command is logged once.

Use them for the commands of the interfaces games open that had no handler
or a nullptr one (hid, am, audio, aoc, caps, mii, set, lm, acc, ssl, bsd and
the nx2 vi2/gsv/gpu/syncpt sessions): a command that returns an interface now
returns one, a command that returns a handle returns an event, so callers no
longer get handle 0 or object 0 back.
