feature: add global driver dispatch as prework for DDI handles extension support

Browse Source 
As per DDI handles extension, global ddi table pointers will be included
in every L0 handle.

This change is focused on initialization of the global objects and reuse
of them within zeGet...ProcAddrTable functions to avoid duplication
of per component ddi table definitions
