Implement an IOSurface-backed pBuffer surface for the Vulkan backend
on Mac, through SwANGLE. ANGLE will pass a raw pointer to Swiftshader
and handle locking/unlocking the IOSurface.

When the user requests an IOSurface Pbuffer with an RGB format, emulate the
missing alpha channel by clearing it to 1.0 and masking reads and writes in
shaders.

This expands the test to check for validation errors and that multiple
formats of IOSurfaces can be read from / rendered to. It fixes a couple
issues in the implementation of the extension too.
Minor fixes in the EGL_ANGLE_iosurface_client_buffer extension text.
Fix a fragile test that was not setting the texture unit a shader is to
sample from.
