MCGR: 2nd corrections/adaptions to MCGR

Adapted handling of 'border' argument from our gradients
for oox export, so that it looks the same.

Also added quite some cases to peserve in-between
GradientStops for current UI implementations to be
able to edit the gradients as usual without losing
the in-between GradientStops.

While we will not be able to modify these, we are
at least able to modify all the other gradient
attributes, including start/endColor.

Done this for TransparencyGradients, too.

Also moved more stuff to the gradient tooling in
basegfx.
