Add lint and test Github Actions

 - Since we don't yet have SDLC pipeline projects for Go libraries or
   for public projects, add in some limited CI validation for PRs to
   this repo including:

   * A build and test stage that generates binaries with the Makefile
     *and* runs make test-coverage to produce coverage (not currently
     used in CI)

     Also uploads these as artifacts

   * Linting through the golangci-lint Github Action

 - NOTE: intially use dorny/test-reporter which produces Github checks,
   which by design doesn't always attach to the right workflow - results
   may show up with golangci-lint. See

   dorny/test-reporter#67
   https://github.com/orgs/community/discussions/24616

   To resolve this, switch to a fork that uses summary instead:
   phoenix-actions/test-reporting#21
