Add function `expand_directory` to gn.

This function expands a directory to a list of files.
This will allow us to do a variety of things, such as:
* Removing our `generate_libcxx_headers` script
* Ensuring that our whole sysroot is in the inputs to a rule.

This is required because the contents of a sysroot are not able to be
stored in the chrome source code because chromeos sysroots can be paths
pointing to the chromeos checkout rather than the chrome checkout.

It also allows us to significantly improve the quality of our third
party libraries, for which we would, after this change, no longer have
to keep the source file list in sync, but instead simply use those third
party libraries as the source of truth.
