Fix MSAA 8x crash: clearValueCount must match attachment count

Browse source 
Render pass begin used 2 clear values but MSAA render pass has 3
attachments (MSAA color, depth, resolve). Vulkan requires clear
value count >= attachment count, causing a driver crash at 8x.

Also fix renderYawM2 reference removed in previous commit.
