Tomaž Vajngerl c703b2d22c basegfx: generalise tuples with template class Tuple2D and Tuple3D 
B2DTuple2D, B2ITuple2D and B2I64Tuple share a lot in common so
we can generalise it as a template class. The same goes for the
3D variants - B3DTuple and B3ITuple.

This is the initial attempt, but doesn't yet generalise all that
is possible.

Add some tests for the tuple variants that test the behaviour of
overloaded operators and other common methods.
