refactor: Unify GTPin initialization logic between APIs

Add support for new GTPin loading logic in OCL path, similar to existing
in L0 - invoking exposed, dedicated API call (OpenGTPinOCL).
- Move logic to shared, including unit tests
- Check whether instrumentation is required on
  clGetPlatformIDs API call, and if yes,
  make a call to OpenGTPinOCL function.
