rust: Add a rust helper for krealloc()memalloc_prof_v3
Memory allocation profiling is turning krealloc() into a nontrivial
macro - so for now, we need a helper for it.
Until we have proper support on the rust side for memory allocation
profiling this does mean that all Rust allocations will be accounted to
the helper.
