Add regression test for the Intel D3D12 driver bug about T2T copy

Browse Source

This patch adds a regression test to dawn_end2end_tests for an
Intel D3D12 driver bug about the T2T copies with specific texture
formats when the source mipmap level is greater than 0.

This patch also does several clean-ups in CopyTests.cpp to support
testing arbitrary texture formats:
1. Initialize the source textures with device.WriteTexture().
2. Set default values for TextureSpec.copyLevel (0),
   TextureSpec.levelCount (1) and TextureSpec.copyOrigin ({0, 0, 0}).
3. Add TextureSpec.format and set the default value for it (RGBA8Unorm).
4. Support initializing and comparing the texture data with arbitrary
   texture format instead of RGBA8Unorm only in CopyTests_T2T.
5. Check all the texels in the related destination texture subresources
   instead of only the copied texels.
