nxtSwapChainNextTexture: make texture a union of ptr, u32, u64

Browse Source 
Making all textures represented by pointers is a problem for Vulkan
where VkImage is a 64bit type and wouldn't fit in a pointer on 32bit
builds. Make texture contain on of each useful type so that each backend
can choose which one it wants to receive.
