checkMesh report AMI coverage on mapped patches

Functionality to add/problem to solve

When doing explicit coupling (e.g. chtMultiRegionFoam) it uses the 'mappedPatch', 'mappedWall' type patches to store the coupling information. For AMI coupling it might be good to know the actual coverage, similar to cyclicAMI. This can be added to checkMesh (which already outputs the weights for cyclicAMI).

Target audience

Explicit coupling using AMI.

Proposal

When run with -allGeometry also output the weights on the AMI for the mapped patch.
