Build a mesh generator which creates an overlaying mesh over the given mesh

[MengnanLi91]

This PR #23513 built a new mesh generator that can generate an overlay mesh with the given mesh block.

Reason

This OverlayMeshGenerator will help meshing the gap between different mesh blocks so that we can do ray tracing in the gap region with relatively low cost. This capability is a part of the efforts to model radiative heat transfer in the gap regions between mesh blocks.

Design

The overlay mesh uses DistributedRectilinearMeshGenerator(DistributedRectilinearMeshGenerator.md) as sub-generator. The generate() method is overloaded and use MeshTools::Modification::scale and MeshTools::Modification::translate to overlay the new mesh with the input mesh. The input parameters for DistributedRectilinearMeshGenerator are all available for OverlayMeshGenerator. The required input parameters of OverlayMeshGenerator are dim (the dimension of the domain) and input (the base mesh we want to overlay).

Impact

This OverlayMeshGenerator will help meshing the gap between mesh blocks. This capability is a part of the efforts to enable ray tracing and radiative heat transfer in the gap region.

I m excited for this.
Meshing by overlaying rectilinear meshes and just cutting parts out is not as difficult conceptually to do as just meshing arbitrary volumes lining up with boundaries exactly and it s a viable approach for many problems.

@roystgnr prefer to review or should I

[roystgnr]

I'll take another pass

I have quibbles about wording and I think some of those header inclusions are atavisms from other files (or older versions?) but I'm not seeing any serious issues.
