Add predicate `ifFeatureEnables` that checks feature is define or not,
and return accordingly boolean value.
Consider some cmake objective targets as features. Populate information
to these targets, and provides in particular file `CMakeFeatures.txt`.
Cpuid, MSR, ACPI and driver VGA in text mode they are.

Project available architectures, project root directory, project current
architecture, project toolchain directory are define in feature module,
and they must to initialize with new function.
The mention above function `featureProjectDataAssign` writes values to these
variables cause them initialize.

The cmake feature module function `bindFeatureToBuild` has overwrite over
the cover function macro.

Feature is enable if variable FEATURE_<feature name> defines and it
caches, and it judges as **enable**.
It influences the FEATURE_<feature name>_IS_ENABLE field in
`CMakeFeature.out` and runfile generation files - all the **enable** features
are mention direct or indirect now.

Add a new macros `createFeatureModuleFunction` that cover functions
definition. If module suspends, generates all blank function. Blank
function is only show a warning about module status. Generate according
body and arguments of function when module is active.

In `outFeaturesToFile` function toolset is appends to a resulting file
(cmake toolchain file or arch, compiler if previous is not specify).
Toolset mention needs to filter available features for a specific
platform. FEATURE_<feature>_IS_ENABLING var also provides when <feature>
already enabled.
Build type is not in toolset now. That means to parse
`CMAKE_BUILD_TYPE` anyway when toolset is processing even if
`CMAKE_TOOLSCHAIN_FILE` is specified.

Implements a new feature module function `outFeaturesToFile` to output all
available features into 'CMakeFeatureOut.txt' file. Format of that file
is set of FEATURE_<feature>_<property> variables like defines in `CMakeCache.txt`.
Will to use as proxy between cmake and configuration tools. Those
utilities read features out file to build configuration kernel tree.

Feature is abstraction around cmake build target used to contains
descriptive information in target properties as name, dependencies, tags
and etc.. Feature creation divided by three processes: start creation
process, fields filling and stop creation process. Start creation
process means passed target is handle now, and stop process is finish to
handle a current feature. Using this way helps to construct correct
features hierarchy and simplify kernel configuration process.
This will use in standalone automating kernel configuration tools:
1. Cmake generate a features file with information about them all.
2. Tool read this file and display features tree.
3. User start to configuring his kernel.
