[Bazel] Fix bazel build, add presubmit (#1973)

* [Bazel] Fix bazel build, add presubmit

* Fixes a missing dep in the Bazel build breaking the host build.
* Automagically finds all board headers.
* Improves presubmit script polish for GH Action readiness.
* Adds a GitHub action workflow for the Bazel build.
* Disable failing checks
* Disables Windows, as there's a mix of real build errors and
  overly-ambitious checks that don't work on Windows.
* Disables extra checks temporarily since it's currently failing.
