Updates to compile Python and Lua bindings

* Updated CMakeList.txt to reference updated output name
* Updated CMakeList.txt for Python and Lua library dependency
* Updated `bindings/open62541.i` to fix init warnings
* Cast `UA_INT64_(MAX/MIN)` and `UA_UINT64_(MAX/MIN)` to export with correct precision
* Changed `UA_NodeIdType` to be external enum for exporting
* Updated UA_StatusCode type handling functions
