Add subcell limiting support for StructuredMesh

[bennibolm]

This PR adds subcell limiting support for Structuredmesh.

Getting the inverse Jacobian makes this PR a bit longer. That's because for TreeMesh, inverse_jacobian is fixed within one element, while it is different for each node for StructuredMesh.
To avoid something like

if mesh isa TreeMesh
    inverse_jacobian = cache.elements.inverse_jacobian[element]
end
for j in eachnode(dg), i in eachnode(dg)
    if mesh isa StructuredMesh
        inverse_jacobian = cache.elements.inverse_jacobian[i, j, element]
    end
    [...]
end

and also avoid unnecessary calls of inverse jacobian in TreeMesh simulations, I dispatched for the mesh type and extracted the code [...] to an inner function (This is also done for e.g. the routine apply_jacobian!).

After this PR, it will be straight forward to add support for P4estMesh.

For now, there is no support for non-conservative systems.

TODO:

• Add or adapt test with non-periodic boundaries

Review checklist

This checklist is meant to assist creators of PRs (to let them know what reviewers will typically look for) and reviewers (to guide them in a structured review process). Items do not need to be checked explicitly for a PR to be eligible for merging.

Purpose and scope

• The PR has a single goal that is clear from the PR title and/or description.
• All code changes represent a single set of modifications that logically belong together.
• No more than 500 lines of code are changed or there is no obvious way to split the PR into multiple PRs.

Code quality

• The code can be understood easily.
• Newly introduced names for variables etc. are self-descriptive and consistent with existing naming conventions.
• There are no redundancies that can be removed by simple modularization/refactoring.
• There are no leftover debug statements or commented code sections.
• The code adheres to our conventions and style guide, and to the Julia guidelines.

Documentation

• New functions and types are documented with a docstring or top-level comment.
• Relevant publications are referenced in docstrings (see example for formatting).
• Inline comments are used to document longer or unusual code sections.
• Comments describe intent ("why?") and not just functionality ("what?").
• If the PR introduces a significant change or new feature, it is documented in NEWS.md with its PR number.

Testing

• The PR passes all tests.
• New or modified lines of code are covered by tests.
• New or modified tests run in less then 10 seconds.

Performance

• There are no type instabilities or memory allocations in performance-critical parts.
• If the PR intent is to improve performance, before/after time measurements are posted in the PR.

Verification

• The correctness of the code was verified using appropriate tests.
• If new equations/methods are added, a convergence test has been run and the results
  are posted in the PR.
