Subject: [PATCH] fix(@angular/build): support reading on-disk files during
 i18n extraction

If an application has JavaScript files that are sourced directly from disk,
the extraction would previously fail due to the i18n extractor only able
to access the in-memory generated JavaScript files. The extractor can now
access both memory and disk-based JavaScript files.
