### Expected Behavior

Show different colors in the icon depending on the resolution and scaling, so it is selecting the best icon size for the screen like File Explorer does.

### Actual Behavior

Windows terminal always shows an orange color, in the menu, tab or quick menu in the task bar. It means it is always choosing the 16x16 ico.

### Importance

This is essential because WSL's new architecture only supports ico files as a shortcut icon. And as we can only ship the 256 one, it will make that Windows Terminal reduce the image and the results are not good.

Reproduce the issue in Windows Terminal by assigning the attached test.ico to a profile and checking the icon in the menu, tab, and taskbar quick menu at different resolutions and scaling levels. Trace the profile icon loading and selection path; done means the displayed icon uses the best matching embedded .ico resolution instead of always selecting 16x16.
