Revert of Add config options to run different GPU APIs to dm and nanobench (patchset #12 id:220001 of https://codereview.chromium.org/1490113005/ )

Reason for revert:
speculative revert to see if it unblocks the DEPS roll

Original issue's description:
> Add config options to run different GPU APIs to dm and nanobench
>
> Add extended config specification form that can be used to run different
> gpu backend with different APIs.
>
> The configs can be specified with the form:
> gpu(api=string,dit=bool,nvpr=bool,samples=int)
>
> This replaces and removes the --gpuAPI flag.
>
> All existing configs should still work.
>
> Adds following documentation:
>
> out/Debug/dm --help config
>
> Flags:
>     --config:	type: string	default: 565 8888 gpu nonrendering
>         Options: 565 8888 debug gpu gpudebug gpudft gpunull msaa16 msaa4
