Kokkos: add support of AMD MI300A

* Use HostMirrorMemorySpace instead of HostSpace to fix compile errors on MI300A

* Replace Kokkos::HostSpace with HostMirrorMemorySpace to fix compile errors on MI300A, since the latter is what Kokkos::DualView use for its host view

* Fix a subtle bug in KokkosDualViewSync() w.r.t MI300A. Suppose we want to sync a petsc VecKokkos v on host. On MI300A, the host copy v_h and the device copy v_d share the memory. So in the old code, we used if (v_dual.need_sync_host()) to skip the device to host memory copy. But I should not skip the exec.fence(). As the device might still have kernels writing v_d, we still need to sync the device/stream to make v_d ready for use on CPU (via v_h).

Unifies all context destructors to have a form of PetscCtxDestroyFn == PetscErrorCode (*)(void **)

Changes the previous subset of destructor APIs that used PetscErrorCode (*)(void *) (mostly those that
used PetscContainer

- Now allows any context to be a PetscObject
- Will provide a cleaner mapping to bindings in other languages
- Simplifies the maintenance of PETSc source code; improves clarity

Not backward compatible, compiler warnings will tell users what functions need to be updated
