This commit enhances the `CompileFn`, which is used to process each entry-point, to support running a passed-in callback (and wait for it to complete) before proceeding with writing the transformed files to disk. This functionality is currently not used. In a subsequent commit, it will be used for passing info from worker processes to the master process that will allow ngcc to recover when a worker process crashes in the middle of processing a task. PR Close #36626
Angular Compatibility Compiler (ngcc)
This compiler will convert node_modules compiled with ngc, into node_modules which
appear to have been compiled with ngtsc.
This conversion will allow such "legacy" packages to be used by the Ivy rendering engine.
