layers: Fix 32-bit Win compilation issue in swapchain layer.

The layer was using an unordered_map<void*, SwpSurface> ... in several
places, but VkSurfaceKHR (unlike many other Vulkan types) isn't a pointer
but a uint64_t.  On Win32, it's trying to push in a uint64_t into a 32-bit
pointer, which the compiler is choking on.  Instead, make the unordered_map
use VkSurfaceKHR.
