Revert "Reland "[ganesh] Fix uniformity error in atlas multitexture lookup SkSL""
This reverts commit c701d191f801ed67d6882232028a61dbeeca9296.
Reason for revert: Some GMs are unreasonably broken following the change (dftext_blob_persp and persp_shaders_aa).
Original change's description:

> > The atlas_multitexture_lookup utility generates SkSL that conditionally
> > selects a texture/sampler pair to sample at a given coordinate. This
> > involves branching on a non-uniform variable. Using sampleLod allows the
> > conditional sampling to remain while satisfying Dawn's uniformity
