Add some generic plumbing and wire it up for the QEMU based Ovmf
platform so that IPv4 and/or IPv6 networking can be turned off from the
QEMU command line.
This is a follow-up to Yuan's patch '[PATCH v1 0/2] Add support to
disable VirtIo net at runtime' which only targeted the virtio network
driver specifically.i
Changes since v2:
- implement Gerd's suggestion to use a DSC include file for network
component overrides
- add Laszlo's ack to patch #1
Changes since v1:
- instead of a NULL class library that calls the Exit() boot service
from its constructor, use a replacement for the UefiDriverEntryPoint
library
