MdeModulePkg, ArmVirtPkg

Which targets are impacted by this bug?

DEBUG, NOOPT, RELEASE

Current Behavior

In the firmware menus in ArmVirtQemu in edk2, and in SbsaQemu in edk2-platforms, firmware menus no longer respond to Enter. Other keys work.

Expected Behavior

Firmware menus should respond to the Enter key as they used to.

Steps To Reproduce

Build either ArmVirtQemu or SbsaQemu normally. Start the built image in qemu. Enter firmware menus. Up and down arrows, and V key (which navigates down) work as normal. Enter key does not work as normal (you cannot select anything). If you are able to navigate to UEFI Shell (e.g. via the pre-menu menu, or via the 's' key), the Enter key still works normally there.
