doc: integrate config xsl transform into doc build

Browse Source 
Documentation for the scenario XML configuration options is pulled from the
schema definition files (xsd) maintained in the misc/config_tools/schema
folder.  Update the doc build process to generate and incorporate the
option documentation.

Scenario Configuration Options
##############################
As explained in :ref:`acrn_configuration_tool`, ACRN scenarios define
the hypervisor (hv) and VM settings for the execution environment of an
ACRN-based application. This document describes these option settings.
.. contents::
:local:
:depth: 2
Common option value types
*************************
Within this option documentation, we refer to some common type
definitions:
Boolean
A true or false value specified as either ``y`` or ``n``. Other
values such as ``t`` or ``f`` are not supported.
Hexadecimal
A base-16 (integer) value represented by a leading ``0x`` or ``0X`` followed by
one or more characters ``0`` to ``9``, ``a`` to ``f``, or ``A`` to ``F``.
Integer
A base-10 value represented by the characters ``0`` to ``9``. The
first character must not be a ``0``. Only positive values are
expected.
String
A sequence of UTF-8 characters. String-length limits or specific
string value restrictions are defined in the option description.
.. comment This configdoc.txt is generated during the doc build process
from the acrn config schema files found in misc/config_tools/schema
