Move checks to different CI workflow

Don't appear to have enough resources in a GitHub runner to run all
tasks in a single runner.

So split them out.

"check" (which runs all lint and tests) can run over every variant on
a single runner, and includes testing the CLI tools.

"build" (which, per variant, does not run tests) doesn't run the tests,
but verifies the code can be built (ignores CLI tools).
