dix: unexport internal QueryFont() function

This function is internal to DIX (used for assembling XQueryFont replies
and not used by any drivers (not even proprietary NVidia), and really
shouldn't ever called by them at all. It's been one the many victims of a
really unthoughtful mass export back 17 years ago.

That'S a necessary step for refactoring the RPC reply mechanics.

Since it's never used by any driver at all, we can easily to this change
within the current ABI level.
