Occlusion query fixes from PR review.

MVKOcclusionQueryCommandEncoderState::beginOcclusionQuery() check for visibility
buffer exhaustion, and if needed, log an error and disable further visibility
tracking for the remainder of the current MTLCommandBuffer.
Create visibility buffer if needed during MVKCommandEncoder::beginMetalRenderPass.
Simplify MVKCommandEncodingContext to PODS.
