This PR is a continuing work for (kata-containers#3679).
This generalizes the previous VFIO device handling which only
focuses on PCI to include AP (IBM Z specific).

Initial VFIO-AP support (#578) was simple, but somewhat hacky; a
different code path would be chosen for performing the hotplug, and
agent-side device handling was bound to knowing the assigned queue
numbers (APQNs) through some other means; plus the code for awaiting
them was written for the Go agent and never released. This code also
artificially increased the hotplug timeout to wait for the (relatively
expensive, thus limited to 5 seconds at the quickest) AP rescan, which
is impractical for e.g. common k8s timeouts.
Since then, the general handling logic was improved (#1190), but it
assumed PCI in several places.
In the runtime, introduce and parse AP devices. Annotate them as such
when passing to the agent, and include information about the associated
APQNs.
The agent awaits the passed APQNs through uevents and triggers a
rescan directly.

Generalize VFIO devices to allow for adding AP in the next patch.
The logic for VFIOPciDeviceMediatedType() has been changed and IsAPVFIOMediatedDevice() has been removed.
The rationale for the revomal is:
- VFIODeviceMediatedType is divided into 2 subtypes for AP and PCI
- Logic of checking a subtype of mediated device is included in GetVFIODeviceType()
- VFIOPciDeviceMediatedType() can simply fulfill the device addition based
on a type categorized by GetVFIODeviceType()

e.g., split_vfio_option is PCI-specific and should instead be named
split_vfio_pci_option. This mutually affects the runtime, most notably
how the labels are named for the agent.

Since shimv2 create task option is already implemented, we need to update the

Also, the ordering is also updated to fit with the code.

This adds /dev/mshv to the list of sandbox devices so that VMMs can
create Hyper-V VMs.
In our testing, this also doesn't error out in case /dev/mshv isn't
present.

When calling `MAKE_KERNEL_NAME` we're considering the default kernel
name will be `vmlinux.container` or `vmlinuz.container`, which is not
the case as the runtime-rs, when used with dragonball, relies on the
`vmlinu[zx]-dragonball-experimental.container` kernel.
Other hypervisors will have to introduce a similar
`MAKE_KERNEL_NAME_${HYPERVISOR}` to adapt this to the kernel they want
to use, similarly to what's already done for the go runtime.
By doing this we also ensure that no changes in the configuration file
will be required to run runtime-rs, with dragonball, as part of our CI
or as part of kata-deploy.

Currently, we only create the new exec process in runtime, this will cause error
when the following requests needing to be handled:
- Task: exec process
- Task: resize process pty
- ...
The agent do not do_exec_process when we handle ExecProcess, thus we can not find
any process information in the guest when we handle ResizeProcessPty. This will
report an error.
In this commit, the handling process is modified to the:
* Modify process tty_win information in runtime
* If the exec process is not running, we just return. And the truly pty_resize will
happen when start_process

This commit adds support for pmu virtualization on aarch64. The
initialization of pmu is in the following order:
1. Receive pmu parameter(vpmu_feature) from runtime-rs to determine the
VpmuFeatureLevel.
2. Judge whether to initialize pmu devices and add pmu device node into
fdt on aarch64, according to VpmuFeatureLevel.
