Build: add a workaround inserting C++ dialect to SYCL preprocessor flags

```bash
$ icpx --version
Intel(R) oneAPI DPC++/C++ Compiler 2025.3.2 (2025.3.2.20260112)
```

By default it uses C++17, but it supports C++20.

With --download-kokkos-kernels, which requires C++20, we need
to explicitly add -std=c++20 to SYCL preprocessor flags to be able
to validate headers of Kokkos-Kernels.

Add automatic generated fortran support for setting and returning contexts

Major cleanup of the code for setting and returning application (previously called user) contexts
- PetscCtx ctx is now the standard for passing in contexts
- PetscCtxRt ctx is the standard for passing out contexts, including context destroy routines based on PetscCtxDestroyFn

Both of these are typedef to void*

Also removed most use of user and userctx for context arguments now consistently named ctx

Improved documentation on PetscCtx and PetscCtxRt and on how to use contexts (including getting them) from Fortran
