Move the logic which volumes are included in the backup job to its own

v2 -> v3: rebased
v1 -> v2:
* implemented the suggestions from Fabian [0]
* incorporated changes that happened in the meantime, most notably the
check for efidisk without omvf bios set
I decided to keep the check for IOThreaded VMs where it is because it
will only trigger if the backup is run with an older qemu version. By
the time this patch series gets applied and shipped I think it unlikely
that this will actually be triggered anymore.
There also seems to be a problem with the way the IFs are nested in that
section. I sent in separate small patch to fix it [1]. I wasn't sure if
I should have implemented that patch here as well. Depending on which
patch gets applied first, the other will need some rebasing.

nit: this is in PVE::QemuServer::Drive now, and we don't want to add new
dependencies from QemuConfig to QemuServer.
Once it's available, the new abstract foreach_volume (will be part of
QemuConfig.pm via AbstractConfig.pm) can also be used here. I'll send
the next version of the series[0] later this week and hopefully it's in
good enough shape to be applied.
