* fix: Update scripts to handle dynamic return type for source/lib
* Update null driver scripts to have dynamic return type and zer API's
* Update scripts to handle dynamic return types for source/loader & default DDI table for zer API's
* Update tracing layer scripts to handle dynamic return type of API's
* Update Validation layer to handle dynamic return types of API's
* Integrate zer namespace in null driver
* Integrate zer namespace in source/lib
* Integrate zer namespace in source/loader
* Integrate zer namespace in validation layer
* Integrate zer namespace in tracing layer
* Track the DriverHandle per Driver as zerDriverHandle, set to nullptr given the driver
  supports DDI Driver EXT, but does not support ZER APIs.
* Enable support for DDI Driver Ext flag etc checks given a handle.
* Backwards compatability guranteed with ze_object.h creation with
  pRuntime set in the loader handle.
* Fix default assignment of zerDriver handle and ddi table and refactor
