SFKokkos: only supports the default stream

CI: fix test example to work with and without CUDA

Change VecGetArrayRead to VecGetArrayWrite as suggested by Hong Zhang

Move assignment of (*V)->offloadmask = PETSC_OFFLOAD_GPU; from VecCreateSeqCUDAWithArray() to only set the flag
if the array is non-NULL, since that is the only case when the flag of PETSC_OFFLOAD_GP

Move assignment of (*V)->offloadmask = PETSC_OFFLOAD_GPU; from VecCreateSeqCUDAWithArray() to only set the flag
if the array is non-NULL, since that is the only case when the flag of PETSC_OFFLOAD_GPU is valid.

Fix wrong use of VecGetArray

VecSet_Seq() should overwrite the memory. Using VecGetArray causes the
array to be copied from GPU to CPU, which is unnecessary.
