[issue37496] Support annotations in signature strings.

[Eric Snow]

New submission from Eric Snow <ericsnowcurrently at gmail.com>:

In early 2014 (3.3), when argument clinic was added, we added support for turning func.__text_signature__ into an inspect.Signature object.  However, at that time we did not add support for annotations (see the nested "parse_name()" in _signature_fromstr().  Annotations should be supported.

I'd expect that PEP 563 (Postponed Evaluation of Annotations) could be leveraged.
