Merge branch 'hongzh/vec-lazy-allocation-on-host' into 'main'

Lazy allocation of the CPU array for GPU vectors

See merge request petsc/petsc!4378

Apply the same change to HIP

Add a benchmark for veccreate

Add Vec/MatGetBindingPropagates().

VecDuplicate() and VecDuplicateVecs() now propagate the bindingpropagates flag.

VecDuplicate() and VecDuplicateVecs() now honor bindingpropagates flag.

Add Vec/MatSetBindingPropagates().

Vectors created by VecDuplicate() and VecDuplicateVecs() now bind the new vector to the CPU if the original vector is bound.

Add -vec_bind_below and -mat_bind_below options.

Kokkos: rename PETSC_OFFLOAD_VECKOKKOS to PETSC_OFFLOAD_KOKKOS since it will also be used for matrices

Zero the GPU array when created
