ECP 5: Deploy production sliding mesh capability with linear solver benchmarking

[spdomin]

Activities:

1. Improve baseline sliding mesh capability at curved surfaces.
2. Evaluate ATDM-based parallel search methods.
3. Establish matrix set-up cost timings.
4. Evaluate possible lagging of matrix update.
5. Evaluate reduction of matrix system by omitting moving block column entries in favor of multiple matrix assembly/solve iterations.
