Add Rosenbrock ReverseDiffAdjoint regression coverage

[ChrisRackauckas-Claude]

Ignore this PR until it has been reviewed by @ChrisRackauckas.

What changed and why

Add a regression test for an out-of-place Rosenbrock23(autodiff = AutoFiniteDiff()) solve differentiated with ReverseDiffAdjoint(). The test covers the failure reported in #4248 without adding a container-conversion workaround to OrdinaryDiffEq.

The underlying bug belongs to ArrayInterface.restructure: a ReverseDiff.TrackedArray template combined with an Array{TrackedReal} source fell through to the generic implementation and lost the tracked-array wrapper. The owner-package fix is already merged in JuliaArrays/ArrayInterface.jl#498, but is not yet in a tagged ArrayInterface release. Do not merge this PR until an ArrayInterface release containing that fix is available.

Failing before

Using released ArrayInterface v7.28.1 with the OrdinaryDiffEq regression test:

Out-of-place Rosenbrock23 with ReverseDiffAdjoint: Error During Test
Cannot convert Vector{ReverseDiff.TrackedReal{...}} to
ReverseDiff.TrackedArray{...}
...
rosenbrock_perform_step.jl:328
Test Summary:                                     | Error  Total
Out-of-place Rosenbrock23 with ReverseDiffAdjoint |     1      1

A direct ArrayInterface reproducer on v7.28.1 showed:

tracked template => Vector{ReverseDiff.TrackedReal{...}}
Array{TrackedReal} template => Vector{ReverseDiff.TrackedReal{...}}
Test Failed: restructure(tracked_template, tracked_values) isa ReverseDiff.TrackedArray

This also confirms why an unconditional downstream aos_to_soa is incorrect: the Array{TrackedReal} template must remain an Array.

Passing after the owner fix

With ArrayInterface commit 58f1c4f9ab203ff6e8c0628575b09b2e1e7edab2 from the merged owner fix:

tracked template => ReverseDiff.TrackedArray{...}
Array{TrackedReal} template => Vector{ReverseDiff.TrackedReal{...}}
2/2 passed

The same OrdinaryDiffEq command then passed:

julia +1.12 --project=test/AD --startup-file=no test/AD/autodiff_events.jl

Out-of-place Rosenbrock23 with ReverseDiffAdjoint | Pass 1 Total 1
Mooncake gradient tests                           | Pass 2 Total 2

Closes #4248

[ChrisRackauckas-Claude]

Superseded CI note for the previous head: the branch has now been rebased onto current master, which includes the DiffEqBase/SciMLBase blocker fix from #4253.

The over-broad OrdinaryDiffEq aos_to_soa workaround has also been removed. Current head 33b4558eac78767db1b33fbac6ea4030fac88436 is test-only and depends on the merged, unreleased owner-package fix JuliaArrays/ArrayInterface.jl#498. Current-head CI should be evaluated separately from the old jobs linked here.
