vdpa: move memory listener to vhost_vdpa_shared

Next patches will register the vhost_vdpa memory listener while the VM
is migrating at the destination, so we can map the memory to the device
before stopping the VM at the source. The main goal is to reduce the
downtime.

However, the destination QEMU is unaware of which vhost_vdpa device will
register its memory_listener. If the source guest has CVQ enabled, it
will be the CVQ device. Otherwise, it will be the first one.

Move the memory listener to a common place rather than always in the
first / last vhost_vdpa.

vdpa: add VhostVDPAShared

It will hold properties shared among all vhost_vdpa instances associated
with of the same device. For example, we just need one iova_tree or one
memory listener for the entire device.

Next patches will register the vhost_vdpa memory listener at the
beginning of the VM migration at the destination. This enables QEMU to
map the memory to the device before stopping the VM at the source,
instead of doing while both source and destination are stopped, thus
minimizing the downtime.

However, the destination QEMU is unaware of which vhost_vdpa struct will
register its memory_listener. If the source guest has CVQ enabled, it
will be the one associated with the CVQ. Otherwise, it will be the
first one.

Save the memory operations related members in a common place rather than
always in the first / last vhost_vdpa.

vhost-vdpa: Add support for vIOMMU.

1. The vIOMMU support will make vDPA can work in IOMMU mode. This
will fix security issues while using the no-IOMMU mode.
To support this feature we need to add new functions for IOMMU MR adds and
deletes.

Also since the SVQ does not support vIOMMU yet, add the check for IOMMU
in vhost_vdpa_dev_start, if the SVQ and IOMMU enable at the same time
the function will return fail.

2. Skip the iova_max check vhost_vdpa_listener_skipped_section(). While
MR is IOMMU, move this check to vhost_vdpa_iommu_map_notify()

Verified in vp_vdpa and vdpa_sim_net driver

virtio,pc,pci: features, fixes

Several features that landed at the last possible moment:

Passthrough HDM decoder emulation
Refactor cryptodev
RAS error emulation and injection
acpi-index support on non-hotpluggable slots
Dynamically switch to vhost shadow virtqueues at vdpa net migration

Plus a couple of bugfixes that look important to have in the release.

In commit a585fad26b ("vdpa: request iova_range only once") we remove
GET_IOVA_RANGE form vhost_vdpa_init, the generic vdpa device will start
without iova_range populated, so the device won't work. Let's call
