Clean up CopyTests

This patch does several clean-ups in CopyTests as a preparation of
supporting buffer-to-texture and texture-to-buffer copies with multiple
texture array layers.
1. Remove the zero-initialization of textures in CopyTests_B2T
2. Use a big buffer that contains the pixel data in all the texture
   array layers instead of several small ones that only contains one
   texture array layer.
3. Make CopyTests_T2T::DoTest() also use CopyTests::TextureSpec as its
   input parameter.
4. Add tests for the copies with multiple texture array layers. In this
   patch we just copy the data once per texture array layer, while in
   the next patch we will be able to copy the data for all the related
   texture array layers in one copy command.
5. Move some helper functions for copy tests to WGPUHelpers.cpp
