refactor: Combine material, measurement and hole handling in Core CKF filter

[andiwand]

Combines the handling of material, measurements and holes in the Core CKF.

---

This pull request includes several changes to the CombinatorialKalmanFilter class in the Core/include/Acts/TrackFinding/CombinatorialKalmanFilter.hpp file to improve error handling, state management, and logging. Additionally, there is a minor change in the MeasurementSelector class to handle empty measurement candidates more gracefully.

Error Handling and State Management:

• Added checks and logging for empty active branches to ensure the filter stops correctly when no branches are active. (Core/include/Acts/TrackFinding/CombinatorialKalmanFilter.hpp) [1] [2]
• Modified the filter to reset and stop properly when all branches are stopped or when certain conditions are met, improving the robustness of the filtering process. (Core/include/Acts/TrackFinding/CombinatorialKalmanFilter.hpp) [1] [2]

Logging Improvements:

• Enhanced logging to provide more detailed information about the state transitions and decisions made during the filtering process. (Core/include/Acts/TrackFinding/CombinatorialKalmanFilter.hpp) [1] [2] [3]

Code Simplification and Cleanup:

• Simplified the handling of material and measurement surfaces by refactoring conditional checks and removing redundant code. (Core/include/Acts/TrackFinding/CombinatorialKalmanFilter.hpp) [1] [2]

Minor Change in MeasurementSelector:

• Updated the MeasurementSelector::select method to return a success result when no measurement candidates are found, instead of returning an error. (Core/include/Acts/TrackFinding/MeasurementSelector.ipp)
