Revert "Transform vertices for distance field glyphs on CPU."

This reverts commit 0215e39d7e415d0530231df6ad20d5f215c72152.

Reason for revert: break intel 540 and HD2000 intel release bots on gltestthreading gm  dftext_blob_pers

Original change's description:
> Transform vertices for distance field glyphs on CPU.
> 
> This allows batching of DF draws with different view matrices.
> 
> For perspective matrices this means the transformed position vertex
> attribute must have w values. Currently, non-perspective DF draws still
> use 2 component positions, though this could be changed in the future.
> Consequently, perspective draws can batch with other perspective draws
> but not non-perspective draws.
> 
> Adds a GM to test batching and reusing the same blobs with both perspective
> and non-perspective matrices.
