radv: Set optimal copy alignment to 1.
I think we set it to 128 for no reason at all. The app is still required to align to the texel size. Note that we prefer 4 bytes for non-formatted buffer->buffer copy, but that isn't in scope for these properties according to the Vulkan spec. It also happens to help hide what looks like an application bug at this point with Baldurs Gate 3.
