Fix issue where M1 GPU does not support reusing Metal visibility buffer offsets
across separate render encoders within a single Metal command buffer (Vulkan submit).

Add MVKCommandEncodingContext to track information across multiple
MVKCommandEncoders, and use it to track temporary visibility buffer and offset.
Add support for more than one temporary visibility buffer per MTLCommandBuffer
when current temporary visibility buffer is exhausted.
