cheri: malloc: Use memcpy for obstack internal copy
Internally obstack used a backward word at a time copy. This can be an aliasing violation and likely slower than memcpy on most targets. The code is a badly written memcpy with performance issues such as the h->object_base indirection cannot be hoisted out of the loop. On CHERI architecture this is needed for copying pointers correctly.
