The files containing the new 'SysmanKmdInterface' has been moved into
the new 'shared' directory in the existing sysman directory. More files
are to be added in this directory which will be used by all the sysman
modules in the sysman and tools directories.

The new classes SysmanKmdInterface, SysmanKmdInterfaceI915 and
SysmanKmdInterfaceXe have been introduced.
A map is maintained in the SysmanKmdInterfaceI915 and
SysmanKmdInterfaceXe class for the sysfs file names.
The access specifier of the function getDrmVersion has been changed from
protected to public so as to use it in the sysman code. This is required
for the SysmanKmdInterface pointer to point to the
SysmanKmdInterfaceI915 and SysmanKmdInterfaceXe accordingly.
The ULTs have been added for the new sysfs file path corresponding to
the i915 and the Xe driver.

Storing config space during sysman init might result in
providing inappropriate properties as config space can be
modified.

This change helps in achieving the following:
- Moves the OS specific code from scheduler_imp.cpp to os specific
files.
- Frees any drm resource, including level zero's before enabling/dis
-abling Debug mode. And once Debug mode is toggled, reinitialize of
level zero occurs.
- If current mode is Debug mode and any other mode is requested by user,
then new mode will be made effective by unsetting debug mode.

Earlier implementation of sysman events API was based on file
creation in the filesystem. Whenever a uevent for some event
which needs to be monitored arrive, at that time a file was
created in the filesystem based on some preinstalled udev rules.
This approach was inefficient as it heavily depends over file
system and second with this approach losing events is always a
possibility.
Now with this change, we are removing our dependency over file
creation in filesystem. Rather we will be using libudev library
to monitor the uevents. This approach could also be extended,
when we want to listen to all the uevents for all the gpu
devices present in the system.
