ScalarizeVecAndMatConstructors: also handle scalar constructors In WGSL you cannot "construct" a scalar from a non-scalar (vec or mat). This modifies ScalarizeVecAndMatConstructors to handle scalar constructors as well, indexing and swizzling the argument to select the first element of the nonscalar. This makes dEQP-GLES2.functional.shaders.conversions.vector_to_scalar.* pass (except those that use bool uniforms which are still unsupported).
