feat(ngcc): support invalidating the entry-point manifest (#35931)

Browse Source 
In some scenarios it is useful for the developer to indicate
to ngcc that it should not use the entry-point manifest
file, and instead write a new one.

In the ngcc command line tool, this option is set by specfying

```
--invalidate-entry-point-manifest
```
