Read ApexMkInfo for modules to be installed.

This piggybacks onto the ApexInfo cquery handler, so we're issuing a
single bazel query call that reads two providers in the starlark expr.

Also rename requiredDeps to makeModulesToInstall to differentiate it from
APEX's required/provided libs in the apex manifest.
