x64 version of winget does install x64 packages on arm system, instead of the arm variant

Brief description of your issue

If a x64 version is ran on a arm64 machine through emulation, winget will install the x64 version of a package instead of the arm64.

While the user usually has the proper version installed, sometimes, especially with bundled winget executables (such as the one on WingetUI) often cause issues.

This issue applies to updates as well, where Winget will install the x64 update over the previous arm package

Steps to reproduce

Run a x64 version of Winget on an arm system through emulation.

Anothger way is to use the bundled winget executable in WingetUI)

Expected behavior

Winget detected the proper system architecture and installed the corresponding packages, regardless of the architecture of the process itself.

Actual behavior

Winget x64 emulated on arm installs x64 packages on arm machines

Environment

winget --info

Start by reproducing the issue with the x64 winget executable under emulation on an ARM64 Windows system, including an update and the bundled WingetUI executable. Trace how the CLI determines system and package architecture; done means it selects the ARM variant for installs and updates rather than the process architecture.
