x11: Remove DRI2 support

Browse source 
DRI2 was hidden behind a legacy-x11 build option back in the 24.2
release. It's now been a year, so let's get on with removing it so we
can simplify our winsys interactions.

This driver supports several platforms: ``android``, ``device``,
``drm``, ``surfaceless``, ``wayland`` and ``x11``. It functions as
a DRI driver loader. For ``x11`` support, it talks to the X server
directly using (XCB-)DRI3 protocol when available, and falls back to
DRI2 if necessary (can be forced with ``LIBGL_DRI3_DISABLE``).
