SL-13361: Distill redundant create_console() code to set_stream().
There are separate stanzas in llappviewerwin32.cpp's create_console() function for each of STD_INPUT_HANDLE, STD_OUTPUT_HANDLE and STD_ERROR_HANDLE. SL-13361 wants to add more code to each. Factor out new local set_stream() function and make create_console() call it three times.
