Feature #11398: deprecate constants

Sometimes old constants are deprecated but still remained for backward compatibilities.
It is not noticed and will be kept forever, with no warnings, though.
So I propose a method Module#deprecate_constant to mark a constant obsolete and emit a warning message when it is referred.

It seems a good idea, for example, we have TimeoutError (instead of Timeout::Error).
