SDPR: Overhauled D2DRenderer to use sal::systools::COMReference

All stuff used from MS with names starting with ID2D1* is COM
API stuff, so referenced and interface-based. I thought about
making this more safe since a while (shared/unique_ptr, ...)
but found no good way to do it.
Also did not want to use CComPtr from MS and expand the devenv
we need on win, so was short before doing an own small smartptr
class. Luckily I asked sberg and he pointed me to the already
existing sal::systools::COMReference which exactly does what
I need here - thanks!
Unluckily I now had to change a lot of code - sigh. I wish
I had known earlier :-/
This change contains the renderer completely adapted to using
that much safer and better ressource control.
Plus I added (even more) comments to try to make more clear
in many plasces what's going on, what is done and why.
