Mangle function names in GLSL. This will be implemented in Metal and SPIR-V in followup CLs.

Rename SkSL's 2D cross product builtin function Note that the 2D cross product isn't defined. There are at least two possible interpretations of what that might mean. This name makes it clearer that we're asking for the length of the resulting vector, if we computed the 3D cross product (assuming Z == 0 for both vectors). It also eliminates name overlap between builtin functions and actual intrinsics.

Implement compile-time optimization for cross(). We need to be careful to distinguish cross(vec3, vec3)--a real built-in intrinsic--from cross(vec2, vec2)--an inline function in sksl_gpu, but not actually a legitimate GLSL intrinsic.
