Deprecate (soft) Py_HUGE_VAL macro

Feature or enhancement

Proposal:

Nowadays, it's just an alias for Py_INFINITY. Using both macros in single codebase, probably, slightly confuse code readers. I think it worth to replace all such cases to Py_INFINITY, as mentioned in this comment.

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere
