Standardize XCTest locations and harnesses (#4005)

- Moves XCTest files to the now-standard location
- Ensures that the harnesses are called RunnerTests for consistency
- Splits the image_picker unit tests out of the UI target into a new unit test target
- Moves existing google_sign_in tests into the harness, since they weren't being run.
  One new test, added since we accidentally stopped compiling the file, was removed
  since it crashed other tests in the suite (which has non-trivial global state, so fixing
  it wasn't feasible here; I've follow up on the PR that added the test).
