At run time (on the *target* machine), acrn-dm depends on "iasl" to build
the ACPI tables for post-launched VMs.
This patch does:
- remove the dependency on ASL_COMPILER, which would only be used at build time
- add a new acrn-dm parameter "--iasl <iasl_compiler_path>"
If "--iasl <iasl_compiler_path>" is specified as the acrn-dm parameter,
acrn-dm uses <iasl_compiler_path> as the path to the "iasl" compiler;
otherwise, "which iasl" is used to detect the "iasl" compiler.
If "iasl" is not found at run time, refuse to launch the post-launched VM
and exit directly.
v2 -> v3:
- use "strlen" rather than "strncmp" to check whether asl_compiler
has been set or not
v1 -> v2:
- remove "iasl_param" and "with_iasl_param" to simplify the logic

The UUID has several usages before:
1, For HV to identify the static VM configuration of post-launched VM.
2, Seed virtualization.
3, Slightly prevent launching malicous VM from SOS as lack of secure
boot.
The UUID is confused to user, user don't understand what it is. And user
don't know where to get/apply the UUID. The worst experience is user
can't launch any VMs w/o re-compile the hv. Everything needs to be
static decided in building phase.
Now we decide to remove UUID and split each usage. For 1st usage, use
vmname as the identifier of static VM configuration. For 2nd one, we
will use --vseed as the new parameter. For 3rd one, will pretect by

In addition to a single OVMF image (OVMF.fd), split images
(OVMF_CODE.fd, OVMF_VARS.fd) can be used to facilitate VM management.
From the OVMF Whitepaper:
The variable store and the firmware executable are also available in
the build output as separate files entitled: "OVMF_VARS.fd" and
"OVMF_CODE.fd". This enables central management and updates of the
firmware executable, while each virtual machine can retain its own
variable store.

--ovmf code=/usr/share/acrn/bios/OVMF_CODE.fd, \

a) If the MMIO device only has MMIO regions and no ACPI Table touched, using

b) If the MMIO device touches ACPI Table, using "--acpidev_pt HID"
Now only support TPM2 MSFT0101 MMIO device pass through through launch script
using "--acpidev_pt MSFT0101". When we want to pass through the TPM2 deivce,
we would not allow to emulate the vTPM2 at the same time. This is becuase
the ACRN-DM emulate the TPM2 as MSFT0101 too. Otherwise, the VM can't boot.
Besides, we could only support one TPM2 device PT and one MMIO device PT.
For TPM2 device PT, the MMIO resources are hard-coded. For the MMIO device PT,
we could pass through the MMIO resources on the cmdline.
ToDo:
1. We may use HID to discover the MMIO regions and ACPI Table instaed of
hard-coded.
2. To identify a MMIO device only by MMIO regions.
3. To allocate virtual MMIO regions in a reserved guest MMIO regions.
