[issue45834] Move runtime except: check to the parser

[Irit Katriel]

New submission from Irit Katriel <iritkatriel at gmail.com>:

The compiler has a runtime check that an "except:" without type can only be the last in the try block:

https://github.com/python/cpython/blob/15409c720be0503131713e3d3abc1acd0da07378/Python/compile.c#L3251

This could be detected by the parser instead.
