Since the UUID is not a *must* set parameter for the standard post-launched
VM which doesn't depend on any static VM configuration. We can remove
the KATA related code from hypervisor as it belongs to such VM type.

With current arch design the UUID is used to identify ACRN VMs,
all VM configurations must be deployed with given UUIDs at build time.
For post-launched VMs, end user must use UUID as acrn-dm parameter
to launch specified user VM. This is not friendly for end users
that they have to look up the pre-configured UUID before launching VM,
and then can only launch the VM which its UUID in the pre-configured UUID
list,otherwise the launch will fail.Another side, VM name is much straight
forward for end user to identify VMs, whereas the VM name defined
in launch script has not been passed to hypervisor VM configuration
so it is not consistent with the VM name when user list VM
in hypervisor shell, this would confuse user a lot.
This patch will resolve these issues by removing UUID as VM identifier
and use VM name instead:
1. Hypervisor will check the VM name duplication during VM creation time
to make sure the VM name is unique.
2. If the VM name passed from acrn-dm matches one of pre-configured
VM configurations, the corresponding VM will be launched,
we call it static configured VM.
If there is no matching found, hypervisor will try to allocate one
unused VM configuration slot for this VM with given VM name and get it
run if VM number does not reach CONFIG_MAX_VM_NUM,
we will call it dynamic configured VM.
3. For dynamic configured VMs, we need a guest flag to identify them
because the VM configuration need to be destroyed
when it is shutdown or creation failed.
v7->v8:
-- rename is_static_vm_configured to is_static_configured_vm
-- only set DM owned guest_flags in hcall_create_vm
-- add check dynamic flag in get_unused_vmid
v6->v7:
-- refine get_vmid_by_name, return the first matching vm_id
-- the GUEST_FLAG_STATIC_VM is added to identify the static or
dynamic VM, the offline tool will set this flag for
all the pre-defined VMs.
-- only clear name field for dynamic VM instead of clear entire
vm_config

For vCAT, it may need to store more than MAX_VCPUS_PER_VM of closids,
change clos in vm_config.h to a pointer to accommodate this situation
Rename clos to pclosids
pclosids now is a pointer to an array of physical CLOSIDs that is defined
in vm_configurations.c by vmconfig. The number of elements in the array
must be equal to the value given by num_pclosids
Add max_type_pcbm (type: l2 or l3) to struct acrn_vm_config, which stores a bitmask
that selects/covers all the physical cache ways assigned to the VM
Change vmsr.c to accommodate this amended data structure
Change the config-tools to generate vm_configurations.c, and fill in the num_closids
and clos pointers based on the information from the scenario file.
Now vm_configurations.c.xsl generates all the clos related code so remove the same
code from misc_cfg.h.xsl.

It seems important that passthru device's max payload settings match
the settings on the native device otherwise passthru device may not work.
So we have to set vrp's max payload capacity as native root port
otherwise we may accidentally change passthru device's max payload
since during guest OS's pci device enumeration, pass-thru device will
renegotiate its max payload's setting with vrp.
