Ard Biesheuvel 970e262949 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.

Ard Biesheuvel d933ec115b OvmfPkg: gather common NetworkComponents overrides in .dsc.inc file 
All QEMU based OVMF platforms override the same set of network
components, to specify NULL library class resolutions that modify the
behavior of those components in a QEMU specific way.

Before adding more occurrences of that, let's drop those definitions in
a common include file.
