payloads/edk2: Add support for passing VBT/GOP driver to edk2

Add Kconfig for passing a VBT file and GOP driver to edk2, and pass a
build param to use them along with the platform GOP driver. This allows
edk2 to initialize the display and change display modes, instead of
being limited to the single mode set by whatever display init method
coreboot might use (libgfxinit, FSP/GOP, VBIOS, etc).

TEST=build/boot multiple google boards spanning several platforms using
the edk2 GOP driver for display init.
