[PATCH v2 0/2] Ovmf: Allow IPv4 and IPv6 to be disabled at runtime

["Ard Biesheuvel" <ardb@kernel.org>]

Add some generic plumbing and wire it up for OvmfPkgX64 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 v1:
- instead of a NULL class library that calls the Exit() boot service
  from its constructor, use a replacement for the UefiDriverEntryPoint
  library
