Chris Dalton fd708655ae Reland "Add tooling support for dmsaa" 
Reland 188443be8d without the DMSAA bots
to ensure nothing else changes.

Original change's description:
> Add tooling support for dmsaa
>
> Adds a "fAlwaysAntiAlias" flag to GrContextOptions that can be set from
> tooling code. When dmsaa is set, SkGpuDevice draws everything
> antialiased. Adds new "gldmsaa" and "glesdmsaa" configs and creates bots
> to run them.
