Revert of Let DM run unit tests. (https://codereview.chromium.org/178273002/)

Reason for revert:
broke tests

Original issue's description:
> Let DM run unit tests.
>   - refactor GYPs and a few flags
>   - make GPU tests grab a thread-local GrContextFactory when needed as we do in DM for GMs
>   - add a few more UI features to make DM more like tests
>
> I believe this makes the program 'tests' obsolete.
>
> It should be somewhat faster to run the two sets together than running the old binaries serially:
>   - serial: tests 20s (3m18s CPU), dm 21s (3m01s CPU)
>   - together: 27s (6m21s CPU)
>
> Next up is to incorporate benches.  I'm only planning there on a single-pass sanity check, so that won't obsolete the program 'bench' just yet.

> Tested: out/Debug/tests && out/Debug/dm && echo ok
