This is like [method@Pango.FontDescription.set_variations], except
that no copy of @variations is made. The caller must make sure that
the string passed in stays around until @desc has been freed
or the name is set again. This function can be used if
@variations is a static string such as a C string literal,
or if @desc is only needed temporarily.
