Sketch DM refactor.

Sketch DM refactor.

BUG=skia:3255
I think this supports everything DM used to, but has completely refactored how
it works to fit the design in the bug.

Configs like "tiles-gpu" are automatically wired up.

I wouldn't suggest looking at this as a diff.  There's just a bunch of deleted
files, a few new files, and one new file that shares a name with a deleted file
(DM.cpp).

I'm going to land this to get some large-scale testing in, then revert it once
enough bots have run.

Just FYI, this seems to have caused the GPU versions of unit tests not to run.
e.g., 

before:

out/Debug/dm --match TestNegativeBlurSigmaGPU
0 GMs x 7 configs, 1 tests, 0 pictures, 0 images
0 tasks left

after:

out/Debug/dm --match TestNegativeBlurSigmaGPU
Skipping nonrendering: Don't understand 'nonrendering'.
Skipping angle: Don't understand 'angle'.
Skipping nvprmsaa4: Could not create a surface.
0 srcs * 3 sinks + 0 tests == 0 tasks
