Add autoscaling option for trust region (and possibly other) methods.

Add tests for SciML/NonlinearSolve.jl#439

The custom enzyme rule for `solve_up` fails when doing sensitivity analysis for a delay differential equation problem. I expected the same rule that works for `ODEProblem `to work for `DDEProblem`...

bug

This issue is for supporting duplicated kwargs for custom rules as mentioned #1459. The example I'm considering is the `callback` keyword argument when differentiating the solution to an ODE problem....

I am trying to use Enzyme to differentiate a function which builds and solves a NonlinearProblem. I believ the issue is with the enzyme extension which is why I'm opening...

enhancement

Same approach that was taken with `ODEProblem `previously. Makes `DDEProblem` mutable and includes a warning if any of the fields are mutated. The reason is to add compatibility with Enzyme.jl

**Describe the bug 🐞** I'm trying to implement a discrete callback which changes the value of a parameter. I'm using ComponentArrays for the parameters as my application is for large...

bug

**Is your feature request related to a problem? Please describe.** I'm attempting to perform sensitivity analysis for a large (100s-1000s parameters+states) DDEProblem. Based on the recommendations, GaussAdjoint seems to be...

**Describe the bug 🐞** The sensitivity for an ODE solve using a Rosenbrock method fails with either `sensealg = InterpolatingAdjoint(checkpointing=true)` or `sensealg = GaussAdjoint(checkpointing=true)` **Expected behavior** I expect the combination...

bug

Still needs: - [x] Pass tests - [ ] Generalize to batchduplicated
