From: Emil Velikov <emil.velikov at collabora.com>
As per the spec hunk:
"The specified offset must be a
multiple of the base alignment of the type of the block member it
qualifies, or a compile-time error results."
v2:
- Fix typo - enhanced-layout > enhanced-layouts
- Prefix uniform tests with ubo
- Add ssbo equivalent tests
- Quote the correct spec hunk in commit msg
