Backport compat for SciMLBase@v2 for FMI@v0.10

[SebastianM-C]

Hi!

FMI@0.10 is still used in some places and recently SciMLBase released v2 (https://github.com/SciML/SciMLBase.jl#v20-breaking-changes). Would it be possible to create a branch based on 0.10.2 on the repo? Then that could be used to backport the SciMLBase version bump by adding a v2 compat and registering 0.10.3 from the commit.

@ThummeTo could we get this bump in ASAP?

[ThummeTo]

Sure.
Just that I get this right: You need a FMI.jl v0.10.3 registered, which is the v0.10.2 but allows for SciMLBase v2 in the project.toml?
If yes, I can do right now.

[ChrisRackauckas]

Yup that's right

[ThummeTo]

Yep, the only related thing that changed were the new ReturnCodes by the ODE solve. I fixed this.
The old tests are running locally now. Registration is triggered.

Should be online now :)
