qga: conditionalize schema for commands requiring fsfreeze
Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the schema to fully
exclude generation of the filesystem freezing commands on POSIX
platforms lacking the required APIs.
The command will be rejected at QMP dispatch time instead,
avoiding reimplementing rejection by blocking the stub commands.
This changes the error message for affected commands from
{"class": "CommandNotFound", "desc": "Command FOO has been disabled"}
to
{"class": "CommandNotFound", "desc": "The command FOO has not been found"}
This has the additional benefit that the QGA protocol reference
now documents what conditions enable use of the command.
