[roll] Roll fuchsia [build] Add build/regenerator script.

Add a new script that implements what `fx-gen-internal` is
currently doing in tools/devshell/lib/vars.sh, i.e.:

- Invoke `gn gen` to regenerate the Ninja build plan.
- Create convenience symlinks for development.

It also patches the Ninja build plan to ensure that whenever
a build file changes, Ninja will invoke the regenerator script
instead of invoking `gn gen` directly.

Future CLs will add other steps to the regenerator script,
including setting up the Bazel workspace.
