common.xml: deprecate the _INT frames

the frame of an altitude is not dependent on how the altitude is being transported (how other fields in the same message are being transported).

ArduPilot has treated these frames to be the same as the non-_INT equivalents in most places for a very long time.

We can save some confusion and perhaps a small amount of flash space if we remove the _INT frames
