Add workaround for depth stencil textures created on non-zero heap on Intel GPUs

This patch always adds RenderAttachment usage for depth stencil
textures which are created on a non-zero heap and initialized with
non-zero value because for such textures, their first usage will
also be as copy destination, so it will also trigger the Intel driver
issue about copying data into a placed depth stencil texture with a
dirty memory.

This patch also combines two pathes that will clear a texture into one
to skip one extra clear.
