Revert "Support large kernels on GPU in matrix convolution effect"

This reverts commit 1ed4391fe7d218caf21754de0932b5e96043621e.

Reason for revert: Looks like some bad images showed up at gold.skia.org and that the ProcessorCloneTest is crashing on Windows bots:

Original change's description:
> Support large kernels on GPU in matrix convolution effect
> 
> Currently matrix convolution falls back to CPU execution for large kernels, due to the argument limit for fragment shaders.
> 
> Now for large kernels, we store them in a texture and sample them in a shader to sidestep the limit.
