[macOS] Add Architecture Priority to Info.plist (#3727)

* Add Architecture Priority to  Info.plist

This allows the app bundle to be launched natively on Arm without the need for Rosetta.

* Remove arch shenanigans in soh-macos.sh.in

Shouldn't be necessary now...

* Add back launching the binary in soh-macos.sh.in

Accidentally removed launching the binary from the script.
