Revert "st/dri2: Implement DRI2bufferDamageExtension"

This reverts commit 492ffbed63a2a62759224b1c7d45aa7923d8f542.

BACK_LEFT attachment can be outdated when the user calls
KHR_partial_update(), leading to a damage region update on the
wrong pipe_resource object.
Let's not expose the ->set_damage_region() method until the core is
fixed to handle that properly.
