refs #31729

Reason

New features allow crack tip to be placed anywhere inside elements whose solutions are enriched. Consequently, it allows correct computation of stress and contour integrals such as J and C(t).

Design

Extended XFEM Repetition Logic in FEProblemBase
A new flag has been added to the FEProblemBase class, complementing the existing mechanism that detects changes in the background mesh. This enhancement ensures that XFEM solutions are repeated not only when the background mesh changes, but also when the cutter mesh advances by an arbitrary increment. Additionally, this resolves a visualization lag present in the previous implementation.

New Material Class: ComputeCrackTipEnrichmentIncrementalStrain
Introduces a new material class designed to enrich the solution field around crack tips while supporting nonlinear material behavior.

Impact

Improve the robustness and accuracy of the XFEM module

You'll need to reference an issue number. I would do it both in the title of your commit message (something like "ref #xxxxxx") as well as in the PR description, which you can edit.

We already have _total_strain_old defined in ComputeIncrementalStrainBase.

You'll need a separate requirement for each test, and those requirements should specifically state the capabilities tested.
