The cached file-system was implemented to speed up ngcc processing, but in reality most files are not accessed many times and there is no noticeable degradation in speed by removing it. Benchmarking `ngcc -l debug` for AIO on a local machine gave a range of 196-236 seconds with the cache and 197-224 seconds without the cache. Moreover, when running in parallel mode, ngcc has a separate file cache for each process. This results in excess memory usage. Notably the master process, which only does analysis of entry-points holds on to up to 500Mb for AIO when using the cache compared to only around 30Mb when not using the cache. Finally, the file-system cache being incorrectly primed with file contents before being processed has been the cause of a number of bugs. For example https://github.com/angular/angular-cli/issues/16860#issuecomment-614694269. PR Close #36687
