For all execution paths where needed, use `BufferObjectHandleWrapper`
instances for registration of BO-handles and try to obtain shared
ownership. This allows both sides of IPC communication to be implemented
in the same process and avoid the double-free problem on a BufferObject
of the same handle.
Currently there are two pairs of such calls:
* `zeEventPoolGetIpcHandle()` + `zeEventPoolOpenIpcHandle()`
* `zeMemGetIpcHandle()` + `zeMemOpenIpcHandle()`
The capability of executing both sides from the same process is useful
for testing but not only.

Changed NumaLibrary to read default policy instead of using
the address-based policy, and remove unnecessary argument.
Removed numaif.h from the repo as it is no longer required.

Unify `getIpcMemHandle()` and `getIpcMemHandles()` and fix the issue of
missing IPC handles registration while reducing copy-pasted code.
Also replace `boHandle` with `boHandleWrapper` to leverage `refCount`
properly and avoid double-free.
