Add diagnostics for unsupported mesh features

[GiudGiud]

Reason

A few features in user meshes are unsupported or undesirable. Many of them can be made with MOOSE meshgenerators even (if you combine them wrong)
We should be able to detect them as early as possible, possibly with a diagnostics object

These include:

• non-planar faces for Ray Tracing
• non-conformality
• non-conformality from adaptively refined meshes
• mixed element types in a subdomain
• unoriented sidesets that flip normals next to subdomains
• unoriented sidesets in general
• sidesets that should be fully external and have an internal component
• full mesh should be covered in sidesets (water-tight by sidesets all around)
• too small volume elements
• too big volume elements
• elements overlapping

Design

A new mesh generators that loops through the mesh in a number of ways (node-loop, elem-loop, etc) to examine features that may be unsupported
It should tell you where to look for the problem

Impact

No need to peer at user meshes in Paraview as hard
