John Stiles 9ea48e3965 Disallow multi-dimensional arrays in SkSL.
GLSL only allows one-dimensional arrays. This CL lowers SkSL's array
dimensionality limit from eight to one, and fixes all the tests that
this breaks. The rest of the code still technically supports
arbitrarily-deep array dimensionality; there are many opportunities for
code cleanup and simplification in followup CLs.
