SiPixelDigiValid::analyse: blade number fix

[schneiml]

This PR fixes #13858.

The number of blades (and also ladders) is read from the GeometricSearchTracker structure. This means there is a new dependency to RecoTracker.

While the changes do fix the crash caused by the geometry dependence of this code, they do not fix the actual problem. The change to the ladder counts is more cosmetic to be consistent with the analogous blade counts; it should remove a number of false 0 entries from the result, but the result is not very meaningful for the upgraded detector anyways.
