bpo-46235: Do all ref-counting at once during list/tuple multiplication (GH-30346) 
When multiplying lists and tuples by `n`, increment each element's refcount, by `n`, just once.

Saves `n-1` increments per element, and allows for a leaner & faster copying loop.

Code by  sweeneyde (Dennis Sweeney).
