gh-122313: Clean up deep recursion guarding code in the compiler (GH-122640) 
Add ENTER_RECURSIVE and LEAVE_RECURSIVE macros in ast.c, ast_opt.c and
symtable.c. Remove VISIT_QUIT macro in symtable.c.

The current recursion depth counter only needs to be updated during
normal execution -- all functions should just return an error code
if an error occurs.

GH-91079: Rename C_RECURSION_LIMIT to Py_C_RECURSION_LIMIT (#108507)

_testcapi and _testinternalcapi constants.

This implements PEP 695, Type Parameter Syntax. It adds support for:

- Generic functions (def func[T](): ...)

- New scoping when the new syntax is used within a class body
- Compiler and interpreter changes to support the new syntax and scoping rules
