cranelift: Add atomic_rmw to interpreter (#5817) (#5856)

Browse Source 
As per the linked issue, atomic_rmw was implemented without specific regard for thread safety.
Additionally, the relevant filetest (atomic-rmw-little.clif) was enabled and altered to fix an
inccorrect call to test function `%atomic_rmw_and_i64` after setting up test function
`%atomic_rmw_and_i32`.
