payloads/external/tianocore: Add build argument for 4G Decode
Add Kconfig option TIANOCORE_ABOVE_4G_DECODE to pass build option to
edk2 to enable or disable "Above 4G Decode". Disabling allows certain Linux
distributions to boot such as Qubes, Zorin and Proxmox.
Requires commit `2f6d4cbcc7fa49462e607baed7626524ccd59ad3` that is
present in the `uefipayload_202107` branch of MrChromebox's edk2
repository.
