i965: Disable clipper statistics when meta operations are in progress.
We don't currently use the clipper statistics, but we'll soon use CL_INVOCATIONS_COUNT to implement the GL_PRIMITIVES_GENERATED query. The number of primitives generated is not supposed to be altered during operations such as glGenerateMipmap. Prevents spec/EXT_transform_feedback/generatemipmap prims_generated from breaking when we start using pipeline statistics registers to implement the GL_PRIMITIVES_GENERATED query in a few commits. v2: Use the BRW_NEW_META_IN_PROGRESS flag for correct state handling.
