fix(@angular-devkit/build-angular): filter explicit external dependen…

…cies for Vite prebundling

To ensure that Vite does not unintentionally attempt to prebundle a module that was explicitly
marked as external (typically via the `externalDependencies` build option), the full list of
externalized imports is now filtered by the dependencies specified within the external configuration.
Vite currently will include a module for prebundling if it is present in the include list even though
it may also be present in the exclude list.
