Can we maybe cache the PI event instead of re-creating from L0 components?

Good call, thanks, fixed.
Avoid creating new Level Zero events. Reset native event handles and put them in the cache instead of removing.

this is strange that it takes an arbitrary integer (I think you only call it with "1")
why is this needed?
Hardcode initial value to 1 because ReferenceCounter is used only for ref counting pi_objects where initial value is always 1.
