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.

The following modifications were done as part of the fix
for warm reset.
1. Release sysman resources before quiscenting the GPU.
2. Add additional checks to confirm quiscenting of the GPU
before launching the diagnostics tests.
3. Fixed warm reset with wait time to allow the changes to be
propagated to the entire GPU PCI tree.
4. Modified the ULT's completely to avoid the usage of MOCKS.
5. Made Diagnostics handle creation per-device from per-SubDevice.

Before performing gpu device reset, first all level zero resources
and gpu device specific resources have to be cleaned up. Also as
after device reset, state of gpu device would be lost.
Hence after performing gpu device reset, level zero device have
to be reinitialized by querying gpu device again.
This change is aimed at reinitializing the level zero resources
after gpu device reset, so that user could continue using level zero
devices after device reset.

This patch does the following:
- Fixes a bug in FsAccess::listDirectory that could return
ZE_RESULT_UNKNOWN_ERROR when no error has occurred.
- Fixes a bug in zesDeviceReset that would reset the device
if force was set to false, even if the device was in use.
- Fixes a bug in zesDeviceReset that would reset the device
if force was set to false without closing the file descriptor.
- Added a releaseResources method method to Device object.
This method does the same thing as the DeviceImp
destructor except it does not free the DeviceImp object
and it does not free the SysmanDeviceImp object.
- Added the releaseResources methods to Mock<Device> object.
- Moved the reset of the debugger out of DriverHandleImp
destructor and into DeviceImp releaseResources.
- Added a releaseEngine method to the EngineHandleContext. This
method frees all the Engine handles.
- On reset, I call the Devcie->releaseResources and
EngineHandleContext->releaseEngines before resetting the device.
- Added a -r (--reset) option to zello_sysman so I
could easily test resets.
With these patches, the L0 Sysman CTS for zesDeviceReset
both pass.
