fix(compiler-cli): ngcc - cope with processing entry-points multiple times (#29657)

Browse Source 
With the new API, where you can choose to only process the first
matching format, it is possible to process an entry-point multiple
times, if you pass in a different format each time.

Previously, ngcc would always try to process the typings files for
the entry-point along with processing the first format of the current
execution of ngcc. But this meant that it would be trying to process
the typings a second time.

Now we only process the typings if they have not already been
processed as part of processing another format in another
even if it was in a different execution of ngcc.
