Rephrasing CopyBufferToTexture validation
Moved some of the validation helper functions from CommandEncoder.cpp
to CommandValidation.cpp. This will make them accessible for
Queue::WriteTexture. Also introduced ValidateLinearTextureData
and ValidateTextureCopyRange which combine already implemented
checks in a way that's defined in WebGPU spec.
