QMP: Introduce query commands dispatch table

The new table is a copy of HMP's table, containing only QObject
handlers.

In the near future HMP will be making QMP calls and then we will
be able to drop QObject handlers from HMP's table.

From now on, QMP and HMP have different query command dispatch
tables.
