feat: Fill track in GX2F

[AJPfleger]

Next generalisation of the Global Chi Square Fitter (GX2F). Now it can fill a track with reasonable trackStates.

This will be followed by an PR including a python example (truth_tracking) to analyse the root-outputs.

Keep in mind, that some of the trackStates still might not be filled with the correct values.

Part 1: Only (very) nitpicky comments
I started a review but realized I have no idea what is going on ^^
I will pass by your office tomorrow before continuing...

[felix-russo]

Looks good to me other than that, but I think a tracking expert should have another look at this

[paulgessinger]

Looks pretty good!

Changes I suggest can be done in a follow-up PR imo, because it's still correct the way it's done right now.
