Revert "Store float value for SkSL settings"

This reverts commit 5f689779d27e7fa914d71fbac74aaf78529ba036.

Reason for revert: Breaking housekeeper bot because it no longer compiles in standalone mode (skia_compile_processors = true in gn args)

Original change's description:
> Store float value for SkSL settings
> 
> If you used 'in float foo' in a runtime effect it would always have the
> value cast to an int. I don't think we saw this in .fp files because
> the cpp generation handled those values directly (if I remember correctly)
>
