In some cases, using the scripts option caused a lot of DescriptionFileUtils.loadDescriptionFile calls which caused a bottleneck during build times.

The why to this is still unknown, but a workaround is to use the resolver from the Webpack compilation instead of the compiler.

Closes #24634


From @fearghalom

On rebuilds, it knocked ~35secs off the time.

…the `scripts` option

In some cases, using the `scripts` option caused a lot of `DescriptionFileUtils.loadDescriptionFile` calls which caused a bottleneck during build times.

The why to this is still unknown, but a workaround is to use the resolver from the Webpack compilation instead of the compiler.

Closes angular#24634
