Xext: purge XGE event masks.

The masks were originally designed to generically handle event masks for
extensions. Since all that is in-server anyway, it's much better writing
custom event masks for those extensions that need it and not providing a
unified mechanism.
XI2 needs more than the current implementation, which is already too complex
for most other extensions. good riddance.
