Benchmark Directory Layout

Bazel

Under bazel the rules for laying out test files are slightly different. Use largetable/render3 as an example.

Put the perf file in current subdirectory (ie largetable) such that the same perf file can be used for each of the sub-subdirectories. (ie largetable/* should all be testable with the same perf file largetable/largetable_perf.spec.ts). Under bazel, typescript protractor spec files must end with .spec.ts or .test.ts.
