ci: enable github actions
This PR enables github actions for oneVPL repository covering project build with clang-12 (mind: latest official release is clang-11, and clang-12 is basically rolling version as of now) and gcc-10.
Triggering configured to run on each merge and on each PR.
Example of the CI run: https://github.com/dvrogozh/oneVPL/runs/2897378213. Mind: on your side run won't be actually triggered till you merge this PR - that's expected behavior on the first PR which adds github actions.
Add Windows workflow support also?
Add Windows workflow support also?
That would be nice, but someone else will need to do that. I don't have ready to go solution for Windows while I do have the one for Linux.
