Currently, based on the file names it's not quite clear whether a given `.spec.ts` file runs benchmark perf or benchmark e2e functionality tests. To disambiguate these, we use new file suffixs. i.e. `e2e-spec.ts` and `perf-spec.ts`. PR Close #34753
The renaming is needed so that js-web-frameworks benchmark test works inside google. PR Close #34258
