ci: Add continuous_integration dependency

[spencer-lunarg]

In effort to reduce the number of limit KhronosGroup minutes we share across repos, this adds dependency to the Continuous Integration CI to only expensive jobs once quicker/smaller jobs run first

[arcady-lunarg]

I don't think this will add very much value: CI jobs mostly succeed, and this just adds latency to every single run. I think it would be better to prune the ci matrix instead, the finding about "gcc" on macos will certainly help us a lot with that.

CI jobs mostly succeed

https://github.com/KhronosGroup/glslang/actions/workflows/continuous_integration.yml?query=is%3Asuccess

there have been 137 failure and 531 successes (so that is a 20% failure rate)

is the latency something you find that would honestly be a bottleneck,
