fix(@angular-devkit/build-angular): ensure unique internal identifiers for inline stylesheet bundling

Within the application builder's template stylesheet processing, internal identifiers are used to track
the incremental bundling status of each inline stylesheet. This identifier now consists of the stylesheet
language, data, and containing file. This ensures that a tracking entry is maintained for each inline
stylesheet and allows for the full cleanup and any incremental bundling resources at the end of the build.
