- Enabled support for zeInitDrivers which combines init and driver get support. - Moved driverHandleGet to be part of Driver class to allow for unit testing of the functionality. - Updated GTPIN init conditions such that init only occurs when pCount > 0 and the driver handle pointer is not null. This ensures that the gtPin init does not trigger during the loader init calling zeInitDrivers and only is called before the first handle is retrieved. - Removed ze_init_flags_t flag from all driverInit functions since this flag is unused in all functions.
