OvmfPkg: Allow runtime control of IPv4 and IPv6 support on QEMU
Wire up the newly added UefiDriverEntrypoint in a way that ties dispatch
of the Ip4Dxe and Ip6Dxe drivers to QEMU fw_cfg variables
'opt/org.tianocore/IPv4Support' and 'opt/org.tianocore/IPv6Support'
respectively.
Setting both variables to 'n' disables IP based networking entirely,
without the need for additional code changes at the NIC driver or
network boot protocol level.
