maximum devscope count in a DMAR structure for statically allocating
drhd_dev_scope array in hypervisor.

Using partial executable paths in the board inspector may cause unintended
results when another executable has the same name and is also detectable in
the search paths.
Introduce a wrapper module (`external_tools`) which locates executables
only under system paths such as /usr/bin and /usr/sbin and converts partial
executable paths to absolute ones before executing them via the subprocess
module. All invocations to `subprocess.run` or `subprocess.Popen`
throughout the board inspector are replaced with `external_tools.run`, with
the only exception being the invocation to the legacy board parser which
already uses an absolute path to the current Python interpreter.

Many of the license and Intel copyright headers include the "All rights
reserved" string. It is not relevant in the context of the BSD-3-Clause
license that the code is released under. This patch removes those strings
throughout the code (hypervisor, devicemodel and misc).

Commit 4a04fcc ("config_tools: skip remapping HW units with no devices under
scope") skips hardware remapping units without any device under its scope in the
config tools, which turns out to only work if the HV is not parsing the DMAR at
runtime.
This patch reverts the previous workaround and fixes the previous issue by
always initializing `dmar_hw_list.hw_ignore` when parsing DMAR. This ensures
that the DRHDx_IGNORE macro will always be emitted while DRHD_COUNT is not
impacted.

It is seen on some platforms that the ACPI DMAR tables will report
remapping hardware units that does not have any device under its scope,
which is not expected by the board inspector previously and thus causes the
tool to generate inconsistent configuration data.
This patch makes the board inspector skip such remapping hardware units. It
does not impact the functionality of the hypervisor as no device is managed
by those skipped remapping units.

This patch reorganize the files of the board inspector as follows.
1. Rename the directory name from `target` to `board_inspector`, in order to
align with the name used in ACRN documentation.
2. Move the scripts that generate the current board XML into the `legacy`
sub-directory. The legacy nodes will be removed after transitioning to the
new board XML schema completely,
3. Add the main script `cli.py` which is the command line interface of the board
inspector.
v1 -> v2:
- Rename `run.py` to `cli.py`.
