qapi: The #optional tag is redundant, drop
We traditionally mark optional members #optional in the doc comment.
Before commit 3313b61, this was entirely manual.
Commit 3313b61 added some automation because its qapi2texi.py relied
on #optional to determine whether a member is optional. This is no
longer the case since the previous commit: the only thing qapi2texi.py
still does with #optional is stripping it out. We still reject bogus
qapi-schema.json and six places for qga/qapi-schema.json.
Thus, you can't actually rely on #optional to see whether something is
optional. Yet we still make people add it manually. That's just
busy-work.
Drop the code to check, fix up and strip out #optional, along with all
instances of #optional. To keep it out, add code to reject it, to be
dropped again once the dust settles.
No change to generated documentation.
