Re-land #2 "Use new vulkan-deps repo for all Vulkan dependencies."

Re-land #2 includes update to licenses.py and removes stale files.

Re-land includes missing headers directory.

This replaces several grouped dependencies with one meta-repo.
The meta-repo will allow us to group multiple inter-dependent
deps rolls into one single roll. This solves the problem of
separate rollers breaking because of the inter-dependencies.
It also allows ANGLE and Chrome to share common bits like the
README and .gitignore files.
