[issue22048] Add weighted random choice to random package

[Dmitry Korchemny]

New submission from Dmitry Korchemny:

Need to have a function for weighted randomization:

given a dictionary: key -> weight (= non-negative number), return a key of the dictionary with the probability proportional to its weight. This capability is basic and is badly missing.
