This PR introduces support for `cr mv` and `cr follow-renames` to
correct `gn` references across the projects when a `BUILD.gn` path
changes. This is a modest introduction to references path correction.
The rewrite does handle relative references though. In source references
are only corrected for the main target, i.e `:basename`, which gets
corrected to the new path base name.
This new approach also attempts to correct gn references to moved
sources, but only for `//` root reference paths. In the future we could
potentially introduce some mechanism handles file renames.
The baseline for this feature was to get the following to build with no
errors:
```
git cr mv components/api_request_helper/ components/api_foo
npm run build -- --target=brave:all
```
As a small detour, this PR adds `npm run format` to these commands, when
wrapping up. This PR also adds a README.md for the `alias` folder.
