Building SuperResolution on ARM64

[ViniKenobi]

Hi!

I was trying to build SuperResolution using windows on snapdragon X Elite and I faced below issue.

error: Invalid triplet name. Triplet names are all lowercase alphanumeric+hyphens.

This is due to vcpkg not handling uppercase letter and ARM64 is written with uppercase.
This is described on below reference for visual studio community.

As a workaround, you must add below property group into .vcxproj file.

It would be important to have this issued fixed, so other user may not face same issue in the future.
