Improvements to maneuver override processing (#6215)

Browse Source 
This change unblocks the osrm-extract debug build, which is
currently failing on a maneuver override assertion.

The processing of maneuver overrides currently has three issues
- It assumes the via node(s) can't be compressed (the failing assertion)
- It can't handle via-paths containing incompressible nodes
- It doesn't interop with turn restriction on the same path

Turn restrictions and maneuver overrides both use the same
from-via-to path representation.
Therefore, we can fix these issues by consolidating their
structures and reusing the path representation for
turn restrictions, which already is robust to the above
issues.

This also simplifies some of the codebase by removing maneuver
override specific path processing.

There are ~100 maneuver overrides in the OSM database, so the
impact on processing and routing will be minimal.
