Add readline.get_pre_input_hook() to retrieve the current pre-input
hook. This allows applications to save and restore the hook without
overwriting user settings.
Much of the information was duplicated in stdtypes.rst; this PR keeps lexical/syntactical details in Lexical Analysis and the evaluation & runtime behaviour in Standard types, with cross-references between the two.
Since the t-string section only listed differences from f-strings, and the grammar for the two is equivalent, that section was moved to Standard types almost entirely.

This simplifies the Lexical Analysis section on Names (but keeps it technically correct) by putting all the info about non-ASCII characters in a separate (and very technical) section.
It uses a mental model where the parser doesn't handle Unicode complexity “immediately”, but:
- parses any non-ASCII character (outside strings/comments) as part of a name, since these can't (yet) be e.g. operators
- normalizes the name
- validates the name, using the xid_start/xid_continue sets

* gh-140550: PEP 793 reference documentation
Since the PEP calls for soft-deprecation of the existing initialization
function, this reorganizes the relevant docs to put the new way of
doing things first, and de-emphasize the old.
Some bits, like the tutorial, are left out of this patch. (See the
issue for a list.)
* Make Py_{SIZE,IS_TYPE,SET_SIZE} regular functions in stable ABI
Group them together with Py_TYPE & Py_SET_TYPE to cut down
on repetitive preprocessor macros.
Format repetitive definitions in object.c more concisely.
Py_SET_TYPE is still left out of the Limited API.
