target/s390x: AP-passthrough for PV guests

Enabling AP-passthrough(AP-pt) for PV-guest by using the new CPU
features for PV-AP-pt of KVM.

As usual QEMU first checks which CPU features are available and then
sets them if available and selected by user. An additional check is done
to verify that PV-AP can only be enabled if "regular" AP-pt is enabled
as well. Note that KVM itself does not enforce this restriction.

Before we were able to bump up the qemu CPU model to a z13, we included
some experimental features during development in the "max" model only.
Nowadays, the "max" model corresponds exactly to the "qemu" CPU model
of the latest QEMU machine under TCG.

Let's remove all the special casing, effectively making both models
match completely from now on, and clean up.

s390x/cpu_models: drop "msa5" from the TCG "max" model

s390x/cpu_models: drop "msa5" from the TCG "max" model

We don't include the "msa5" feature in the "qemu" model because it
generates a warning. The PoP states:

"The message-security-assist extension 5 requires
the secure-hash-algorithm (SHA-512) capabilities of
the message-security-assist extension 2 as a prereq-
uisite. (March, 2015)"

As SHA-512 won't be supported in the near future, let's just drop the
feature from the "max" model. This avoids the warning and allows us for
making the "max" model match the "qemu" model (except for compat
machines). We don't lose much, as we only implement the function stubs
for MSA, excluding any real subfunctions.

This defines 5 new facilities and the new 3931 and 3932 machines.
As before the name is not yet known and we do use gen16a and gen16b.
The new features are part of the full model.

The default model is still empty (same as z15) and will be added
in a separate patch at a later point in time.

Also add the dependencies of new facilities and as a fix for z15 add
a dependency from S390_FEAT_VECTOR_PACKED_DECIMAL_ENH to
S390_VECTOR_PACKED_DECIMAL.
