new propagateToPlane code.

* Add VDT support to Matriplex, mostly to work on Matriplex scalar types.
  - Functions are prefixed as fast_xyzz(), same as in VDT.
  - Controlled by define MPLEX_VDT. Additionally, if MPLEX_VDT_USE_STD is also
    defined, the fast_xyzz() functions fall back to using std:: variants.
    This is useful for performance comparisons.
  - Add reduction operator and an assigner class / method to extract scalars
    (one i,j element) or to assign to it.

* Massage propagateToPlane low level implementation
  - Use the new Matriplex functionality to simplify code.
  - Remove the nmin, nmax indices initially introdcued to support GPU code
    (this was actually a wrong way ... Matriplex does support MatriplexVectors
    that should have been used instead -- and extended as needed).

…om Matriplex.

- Collect unique ModuleShapes in MkFitGeometryESProducer and store them
in a vector for each LayerInfo.

- Add shape_id member to ModuleInfo (and remove half-legtn that is now available
from the ModuleShape).

- Add LayerInfo::m_has_charge to the prinout.

- List ModuleShapes when detailed TrackerInfo is requested.

- TrackerInfo::print_tracker() now takes additional argument 'precision' that
determines number of decimal places to use for printing of module/shape
parameters.
