Pete Bacon Darwin 141fcb95a4 refactor(localize): use the FileSystem from ngtsc (#36843)
This commit makes the leap from its own custom baked `FileUtils`
solution to the fully formed `FileSystem` that is used in the compiler-cli.

This makes testing more straightforward and helps to ensure that the tool
will work across operatings systems.

Also, going forward, it will allow the localize project access to other useful
code from the compiler-cli, such as source-map handling.
