Add a General Plane Cutting Mesh Generator for 3D Meshes

[miaoyinb]

Reason

PlaneDeletionGenerator is general but it does not modify the existing elements so that the cross-section is usually "zigzag". Although 2D mesh cutting (trimming) capabilities are available in MOOSE through #23847. It would be helpful to extend such capabilities to 3D meshes.

Design

As TET4 elements are inevitably generated during 3D cutting, a simplified approach will be used: (1) convert the 3D mesh to all-TET4 meshes by splitting non-TET4 elements. (2) then perform the cutting by a converted the remainder of the cut TET4 element into 1~3 TET4 elements.

Note the mesh generator only works for first-order elements now.

Impact

Provide users another powerful tool in the mesh system to enable more complex meshing capability using MOOSE's intrinsic mesh generation capabilities.
