Starting from QEMU-6.2 enum members are reported as an array of objects
under new name "values" so that extra data can be reported for each
member.
Modify the code so that we prefer 'members' and skip 'values' completely
if we've used 'members'.

When you set metadata with type element like the following:
dom.setMetadata(libvirt.VIR_DOMAIN_METADATA_ELEMENT, "<test/>", 'abc', "HAHAH", 0)
Then for `virsh event --all`, then it will output this message:
event 'metadata-change' for domain 'rhel9': element HAHAH
The message is ambiguous since it looks like the params for
metadata-change event is the element HAHAH. Actually that means the type is
element while the url is HAHAH. Let's make it more clear.

QEMU version 3.1 introduced PV_SEND_IPI CPUID feature bit under
commit 7f710c32bb8 (target-i386: adds PV_SEND_IPI CPUID feature bit).
This patch adds a new KVM feature 'pv-ipi' to disable this feature
(enabled by default). Newer CPU platform (Ex, AMD Zen2) supports
hardware accelation for IPI in guest, to use this feature to get
better performance in some scenarios. Detailed about the discussion:
https://lkml.org/lkml/2021/10/20/423
To disable kvm-pv-ipi and have libvirt add "-cpu host,kvm-pv-ipi=off"
to the QEMU command line, the following XML code needs to be added to the
guest's domain description:
<features>
<kvm>
<pv-ipi state='off'/>
</kvm>
</features>

It may happen that qemuProcessStop() is called from "qemu-event"
thread. But this thread doesn't have any virIdentity set
(virIdentity being thread local) and therefore it may be unable
to open connection to secondary drivers. It is unable to do so
in split daemon scenario, because in there opening a connection
is coupled with copying current thread identity onto the
connection. Code-wise, virIdentityGetCurrent() returns NULL which
in turn makes virGetConnectGeneric() fail. This problem does not
occur in monolithic daemon scenario, because no identity copying
is done there.
Long story short, inability to open secondary driver connection
can lead to unwanted results. Therefore, do what
qemuProcessReconnectHelper() does - set the new thread identity
to be the one of the caller.

In some cases the worker func running inside the pool may rely on
virIdentity. While worker func could check for identity and set
one it is not optimal - it may not have access to the identity of
the thread creating the pool and thus would have to call
virIdentityGetSystem(). Allow passing identity when creating the
pool.

This is a typical example of what can go wrong when sending out
an old patch. Back in January, when I was writing
qemuProcessHandleMemoryDeviceSizeChange() events were sent to the
worker pool thread using virThreadPoolSendJob(). Then, in July a
helper was introduced (qemuProcessEventSubmit()) but since my
code was not committed and I did not pay attention my code wasn't
updated. Later, when I merged my code it uses the old approach.
BTW: this also fixes a possible double free which I completely
missed when writing the code ~10 months ago.
