George Kalpakas 772ccf0d9f feat(ngcc): support reverting a file written by FileWriter (#36626)
This commit adds a `revertFile()` method to `FileWriter`, which can
revert a transformed file (and its backup - if any) written by the
`FileWriter`.

In a subsequent commit, this will be used to allow ngcc to recover
when a worker process crashes in the middle of processing a task.
