OvmfPkg/QemuBootOrderLib: add StoreQemuBootOrder()
The function reads the boot order from qemu fw_cfg, translates it into
device paths and stores them in 'QemuBootOrderNNNN' variables. In case
there is no boot ordering configured the function will do nothing.
Use case: Allow applications loaded via 'qemu -kernel bootloader.efi'
obey the boot order.
