[kitrt] Fixes for numpy extension module (lanl#57)

* [kitrt] Fixes for numpy extension module

 - Renamed kitrt.c to kitrt.cpp
 - Removed system allocators from extension module
 - Fixed typo in mem_realloc method name for both cuda and hip
 - Fixed signature for enable/disable mem handler

* Unconditionally include kitrt.h.
Fixed whitespace errors.
