gallium: add PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVE
To be able to properly distinguish between GL_ANY_SAMPLES_PASSED
and GL_ANY_SAMPLES_PASSED_CONSERVATIVE.
This patch goes through all drivers, having them treat the two
query types identically, except:
1. radeon incorrectly enabled conservative mode on
PIPE_QUERY_OCCLUSION_PREDICATE. We now do it correctly, only
on PIPE_QUERY_OCCLUSION_PREDICATE_CONSERVATIVE.
2. st/mesa uses the new query type.
Fixes dEQP-GLES31.functional.fbo.no_attachments.*
