Subject: NetworkPkg: introduce include file for dynamic PCDs

Introduce an include file with dynamic PCDs to simplify the usage of
the network stage. This allows us to stop manually adding
`PcdIPv4PXESupport` and `PcdIPv6PXESupport` to the DSC file.

`NETWORK_IP4_ENABLE` and `NETWORK_IP6_ENABLE` are not used because
PXEv4 and PXEv6 boot support can be controlled from the QEMU command
line.
