dependencies/ui.py: Improve Vulkan detection on Windows

There now exists a Windows Vulkan SDK for ARM64, and the latest Vulkan
SDKs for x64 Windows also provides ARM64 libraries and binaries for
cross-builds (and vice-versa).

So, now we have the following in the Vulkan SDKs:

* Bin-ARM64 and Lib-ARM64 in x64 Windows SDKs that contains ARM64
  Vulkan binaries and libraries.
* Bin-X64 and Lib-X64 in ARM64 Windows SDKs that contains x64 Vulkan
  binaries and libraries
* SDKs after 1.4.x (or so) no longer ships 32-bit Windows binaries and
  libraries.

This updates the Vulkan detection logic to account for these differences
so that the correct library is picked up upon linking on Windows,
especially when cross-compiling ARM64 binaries on x64 Windows, and vice
versa, while maintaining compatibility with native and 32-bit builds.
