Steven Wu 756e53967e [TEST-ONLY] Add utility to perform explicit module build
Add a script to build all dependencies for explicit module build in one
step. This reduces the boiling plate code needed to write a test for
explicit module build and allows the test to be more cross platform and
resilient to module dependencies changes.
