- Fixed IPC Event pools that are allocated for a single device such that
when opened thru IPC only that device handle can be used by the process
which opened the IPC event pool.
- IPC Event handle includes numDevices as a field to determine if the
root device index is the only index allowed for this event pool.

1. Reposition event pool code
- Implementation of event pool methods should be placed in event pool file
2. Change event pool and event classes
- move all class variables to base classes as protected
- add needed setters and getters for runtime
- add extended mocks and whiteboxes for unit tests
- tests using base or mock class when needed
3. Correct event creation in unit tests
- use HW specific timestamp type
- HW unit tests are using template timestamp type for event creation
- other tests are using helper to create event

1. If cpu based copy is used, it is possible that copy time is
less than device timestamp resolution. In this scenario, this patch
returns 1 instead of 0.
2. This patch also fixes usage of CPU time instead of CPU timestamp
for end timestamp calculation.

- Given Device Allocated IPC Event Pool, the open IPC event pool process
must allocate the event pool as a device buffer or usage of the memory
will fail.
- Pass deviceAlloc flag thru the IPC Event Pool Handle to enable the
child processes to allocate the correct memory type.
- Pass isHostVisible flag thru IPCEvent Pool Handle to indicate if the
event pool must be allocated as host visible regardless of the
allocation type.

This fix unifies setting event properties in event pool, so they are shared
betweem all event pool devices.

If a handle cannot be obtained, like PRIME_HANDLE_TO_FD, then
properly check for the error and propagate it upwards.

Currently event pools are allocated in system
memory if HOST_VISIBLE flag is being set.
With this change such event pool will be
allocated in device memory if DC flush is not
allowed.

- Properly check for IPC event handle flag to determine if the event
pool memory is sharable between processes.
- Given Host Visible Event Pool, a check is done to determine if the
Host memory can be shared between the processes.
- Enabled handling if Event Host Memory is shareable for DRM
- If Event Pool Memory is Not shareable, then retrieving the IPC Event
Pool Handle returns unsupported.

ie. number of root device indices not more than 16

- Add getMemoryManagerType to check which memory manager has been init
to determine if Linux + WDDM memory manager is in use.
- Add isNTHandle to test and verify if a handle is an NT handle during
L0 Open IPC Handle.
