Subject: [PATCH] fix(@angular/build): use consistent path separators for
 template HMR identifiers

To ensure that component HMR identifiers match correctly during an update,
the path element of the identifier generated by the build system will now
convert all windows path separators into POSIX separators. This provides
matching behavior to the AOT compiler's identifier generation process.
