qga: centralize logic for disabling/enabling commands

It is confusing having many different pieces of code enabling and
disabling commands, and it is not clear that they all have the same
semantics, especially wrt prioritization of the block/allow lists.
The code attempted to prevent the user from setting both the block
and allow lists concurrently, however, the logic was flawed as it
checked settings in the configuration file separately from the
command line arguments. Thus it was possible to set a block list
in the config file and an allow list via a command line argument.
The --dump-conf option also creates a configuration file with both
keys present, even if unset, which means it is creating a config
that cannot actually be loaded again.

Centralizing the code in a single method "ga_apply_command_filters"
will provide a strong guarantee of consistency and clarify the
intended behaviour. With this there is no compelling technical
reason to prevent concurrent setting of both the allow and block
lists, so this flawed restriction is removed.

qga: conditionalize schema for commands not supported on other UNIX

Rather than creating stubs for every command that just return
QERR_UNSUPPORTED, use 'if' conditions in the QAPI schema to
fully exclude generation of the commands on other UNIX.

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.

This also fixes an accidental inconsistency where some commands
(guest-get-diskstats & guest-get-cpustats) are implemented as
stubs, yet not added to the blockedrpc list. Those change their
error message from

{"class": "GenericError, "desc": "this feature or command is not currently supported"}

to

The final additional benefit is that the QGA protocol reference
