feat(ivy): implement listLazyRoutes() for ngtsc (#27697)

This commit uses the NgModuleRouteAnalyzer introduced previously to
implement listLazyRoutes() for NgtscProgram. Currently this implementation
is limited to listing routes globally and cannot list routes for a given lazy
module. Testing seems to indicate that the CLI uses the global form, but this
should be verified.
