gh-133767: Fix use-after-free in the unicode-escape decoder with an error handler (GH-129648)
...
If the error handler is used, a new bytes object is created to set as
the object attribute of UnicodeDecodeError, and that bytes object then
replaces the original data. A pointer to the decoded data will became invalid
after destroying that temporary bytes object. So we need other way to return
the first invalid escape from _PyUnicode_DecodeUnicodeEscapeInternal().
_PyBytes_DecodeEscape() does not have such issue, because it does not
use the error handlers registry, but it should be changed for compatibility
with _PyUnicode_DecodeUnicodeEscapeInternal().

gh-131421: fix ASDL grammar for Dict to have an expr?* keys field ( #131419 )
...
In the `ast` documentation for Python:
* https://docs.python.org/3/library/ast.html#ast.Dict
it is made clear that:
> When doing dictionary unpacking using dictionary literals the expression to be expanded goes in the values list, with a `None` at the corresponding position in `keys`.
Hence, `keys` is really a `expr?*` and *not* a `expr*`.
