fvOption 'geometric' selection not very geometric for moving meshes

Functionality to add/problem to solve

selectionMode geometric; does not update for mesh motion / mesh topo changes / field changes

Target audience

fvOption using the geometric selection method.

(also #2717)

Proposal

• detect mesh motion and update selection
• detect mesh topo changes and update selection
• optionally disable selection update to freeze the set of cells?
• detect field changes when using fieldToCell?
• allow non-cellSet commands inbetween
• integrate into setFields?

What does success look like, and how can we measure that?

• not slower if static mesh
