Add support for mat2-to-ivec4 conversions in SkSL. The fuzzer quickly discovered that the newly introduced mat2-to-vec4 conversion code did not account for integer vectors. We now handle `ivec4(mat2)` casts properly. This required some non-trivial restructuring of the logic, but in the vast majority of cases, the types will match and the end result will be identical.

Add hints to slicing-constructor error messages. This is intended to make it easier for users porting GLSL code with slicing constructors; the error message should make it clear that a swizzle can be used here instead.
