app: in GimpBacktrace Windows backend, set main-thread name

When initializing the GimpBacktrace Windows backend, set the name
of the current thread (which is assumed to be the main thread) to
the program's name, to match its name on Linux.  We normally rely
on the SET_THREAD_NAME exception to set thread names on Windows,
which isn't raised for the main thread.
