56da6c91b7 Fix parsing of tuple with named expression as context manager 
Because the ‘with’ item grammar disallows named expressions, CPython
parses ‘with (a := 0, b := 1):’ as a tuple rather than two ‘with’
items.

bfd847d04c Parse Python 3.9+ parenthesized context managers 
Since the upstream grammar for this is not LR(1), we abuse LALRPOP
macros and the Into/TryInto traits to build a cover grammar that
converts to either tuples or `with` items after additional validation.
It’s annoying and ugly, but something like this is basically our only
option short of switching to a more powerful parser algorithm.

Fixes #4145.
