Windows installer: Improve architecture detection

Show an appropriate error if the ARM64 installer is run on non-ARM
Windows or if the x64 installer is run on a 32-bit system, and set the
correct architecture in `CurrentVersion\Uninstall` registry key.

Also fix `x86`/`x64` being swapped in the registry
