Revert of Refactored TestExpectations out of Telemetry and into content/test/gpu. (patchset #5 id:70001 of https://codereview.chromium.org/1224233005/)

Reason for revert:
I believe this patch broke the blink_perf.canvas perf test on Linux, Mac and Windows:

Original issue's description:
> Refactored TestExpectations out of Telemetry and into content/test/gpu.
>
> The GPU tests are the primary user of Telemetry's TestExpectations,
> and it turns out they can be implemented entirely in the code using
> Telemetry, rather than Telemetry itself. For this reason, move them
> into content/test/gpu.
>
> Refactored the GPU tests to all derive from a common set of base
> classes implementing support for test expectations. Verified that
> skipping tests, expected failures, and flaky test handling all work.
> More tests of test expectations are needed, and will be added in later
> CLs; this one is too large already, but can't be broken up further.
>
> Fixed up two WebGL perf tests that were relying on test expectations
> to skip the pages on specific GPUs, and added a hook to Telemetry's
> browser_info to enable this.
>
> This CL loses one valuable test,
> testHandlingOfCrashedTabWithExpectedFailure, from
> page_run_end_to_end_unittest.py. It will be reintroduced in a later CL.
>
> A subsequent CL will redesign TestExpectations. This CL is intended to
> be a refactoring with no behavioral changes.
>
> Ran telemetry_unittests, telemetry_gpu_unittests,
> telemetry_perf_unittests, and all GPU tests locally to verify.
