Upload images from cc::GpuImageDecodeCache using something better than glTexImage2d

Project Member Reported by enne@chromium.org, Oct 5 2017 
This is not the most efficient method for uploading images, so we probably need to pull the upload step out of Skia and do it ourselves using other mechanisms.

Alternatives:
1- GMBs (like zero-copy or one-copy), saves a copy on the client side, and can make the service-side more efficiten
2- MapTexSubImage2DCHROMIUM (command-buffer specific), saves a copy
3- PBOs (on ES3), may be cheaper service side, but still requires extra copy

Separately, we should consider splitting large uploads. Possible with 2 and 3, but not with 1.

With OOP Raster, this won't really be too interesting. Closing this out.
