Some tests around surface creation and snapshotting with color space

Some tests around surface creation and snapshotting with color space

Verify the rules that we're converging on for surfaces:
- For 8888, we only support sRGB-like gamma, or no color space at all.
- For F16, we require a color space, with linear gamma.
- For all other formats, we do not support color spaces.
