Core/Movement: Add new SplineChainMovementGenerator that allows accurate replication of sniffed waypoints in static sequences, along with DB facilities that allow loading of waypoints from DB.

(cherry picked from commit 6d00d3f28380dd0811a18913450b1dc4f07fef48)

Merge remote-tracking branch 'Treeston/3.3.5-splinechains' into 3.3.5 (PR #17946)
(cherry picked from commit 20f483967fb3a430fbd54148c08b6d8e8937daac)

Core/Movement: Add a convenience default ctor to SplineChainResumeInfo, and fix PCH build in some configurations (zzz why do we even keep Appveyor and Travis around).
(cherry picked from commit 4fa646c0b2ae3261e7fab249f4177900d4c8d013)

PCH build fix. Again.

(( Alright, you made me waste 20 minutes of my life on a full nonPCH rebuild of the core now. ))
(( I hope you're happy. ))
(cherry picked from commit 4a1a460241acf511467decd92d2a30e19927d74d)
