[PATCH] ArmVirtPkg: handle NETWORK_TLS_ENABLE in ArmVirtQemu*

["Laszlo Ersek" <lersek@redhat.com>]

Port the [LibraryClasses], [PcdsFixedAtBuild] and [Components] settings
that are related to NETWORK_TLS_ENABLE from OvmfPkg to ArmVirtPkg.
ArmVirtXen is not modified because it doesn't include the edk2 network
stack.

(This change is now simpler than it would have been when TianoCore#1009
was originally filed, due to ArmVirtPkg consuming the NetworkPkg include
fragments meanwhile, from TianoCore#1293 / commit 157a3b1aa50f.)

The usage hints from "OvmfPkg/README", section "HTTPS Boot", apply.
