bpo-40939: Remove documentation for `PyParser_*` & add porting notes (GH-26855) (GH-26898)

I tried to be relatively thorough and give lots of links.
One reason is that this wasn't deprecated very long; also it seems people running into this tend to not be familiar with similar APIs.

(cherry picked from commit 29987f72650b7cccee4df216c8297e8484a44e6a)

-   Parse Python source code from *str* using the start token *start* according to
-   the *flags* argument.  The result can be used to create a code object which can
-   be evaluated efficiently. This is useful if a code fragment must be evaluated
-   many times. *filename* is decoded from the :term:`filesystem encoding and
