Migrate from Travis CI to GitHub Actions

[CamStan]

Description

Migrate from using Travis CI to GitHub Actions.

Will trigger on all branch pushes as well as pull requests to the dev branch.

Runs checkpatch.

Tests installing dependencies with Spack, building UnifyFS, and running the unit tests across multiple GCC compiler versions (7, 8, 9, 10, 11).

Motivation and Context

• More immediate results for build results/errors, style issues, and smoke tests when creating PRs
• Travis CI no longer being used.

How Has This Been Tested?

Ran and passed in forked repo (here)

Looks like one quick change I need to add.

Thanks, @CamStan . I'll let it sit a day or so before merging in case others want to review.

@adammoody, sounds good! It should be good now. At some point after being merged I might need you to check the repo's settings on actions and branch protections since I can't view settings (can do this in the next meeting).
