Subject: Revert "Enforce our rules about valid images when making textures"

This reverts commit 7035f3c466826a4116e2f31deb64d1645ea9441b.

Reason for revert: Need to revert earlier change to fix DEPS roll.

Original change's description:
> Enforce our rules about valid images when making textures
>
> I'm working to make GrUploadPixmapToTexture more robust
> and easier to follow. This is one step on that journey.
