deps: cherry-pick 9a49b22 from V8 upstream 
Original commit message:
  Fix alloc/dealloc size mismatch for v8::BackingStore

  On newer compilers the {operator delete} with explicit {size_t}
  argument would be instantiated for {v8::BackingStore} and used
  in the destructor of {std::unique_ptr<v8::BackingStore>}. The {size_t}
  argument is wrong though, since the pointer actually points
  to a {v8::internal::BackingStore} object.
  The solution is to explicitly provide a {operator delete}, preventing
  an implicitly generated {size_t} operator.

  Bug:v8:11081
