feat: EDM4hep plugin, Track reader + writer

[paulgessinger]

This PR adds a writer and a reader for TrackContainer to and from EDM4hep track objects and track states.

This is unfortunately not lossless:

• EDM4hep only accepts perigee parameters, so all track state hits get converted to bound parameters relative to a perigee centered at the hit position. When reading track states back in, this representation is kept (as there is no way to recover the original sensor).
• The track parameters are converted to the LCIO parametrization, and the covariance is stored as a lower left triangle

Since I want the conversion functionality to live in Core, I add an EDM4hep plugin here, that the existing EDM4hep IO example now uses. The Example-specific functions are kept where they are, but TrackContainer and some helper now live in a Core plugin.

I'm also changing over the MultiTrajectory writer to use the new covariance and parameters conversion.

nice work! code looks very clear and clean to me. left two minor comments

I found some potential further issues locally on macOS. Taking this WIP until fixed.
