If the shared allocation hasn't been removed up to this point,
then remove it when freeing the pointer.
No need to check if ptr is still in the map, as erase would
automatically return 0 if not found.

- 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.

properly check for the error and propagate it upwards.

This change replaces unneeded copying of std::vectors
with usage of const references. Furthermore, it adds
reserve() call before filling the container via push_back().

- 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.

When using implicit scaling, device allocations may have
more than one internal allocation created internally. In that case,
a separate dma-buf handle per internal allocation needs to be
exported.
So introduced two driver experimental extensions to export and
import more than one IPC handle:
- zexMemGetIpcHandles
- zexMemOpenIpcHandles
