Platform build fails on Windows due to definition of dllimport function not allowed

HPCC Windows build failed :
20:50:13 53>..\..\..\..\HPCC-Platform\esp\services\ws_machine\componentstatus.cpp(335) : error C2491: 'getComponentStatusFactory' : definition of dllimport function not allowed

To avoid the error " #define COMPONENTSTATUS_API __declspec(dllimport)" should in in *.hpp instead of *.ipp file
