bpo-45431: Rename CFrame to _PyCFrame in the C API (GH-31584)

directly the private _PyCFrame structure.

bpo-46816: Remove declarations for non-__STDC__ compilers (GH-31466) 
After Python switched to C11, there is a guarantee that every compiler
conforms to ISO C so checks of __STDC__ have no sense.

bpo-46748: Don't import <stdbool.h> in public headers (GH-31553) 
<stdbool.h> is the standard/modern way to define embedd/extends Python free to define bool, true and false, but there are existing applications that use slightly different redefinitions, which fail if the header is included.

It's OK to use stdbool outside the public headers, though.

bpo-45412: Add _PY_SHORT_FLOAT_REPR macro (GH-31171) 
Remove the HAVE_PY_SET_53BIT_PRECISION macro (moved to the internal
C API).

* Move HAVE_PY_SET_53BIT_PRECISION macro to pycore_pymath.h.
* Replace PY_NO_SHORT_FLOAT_REPR macro with _PY_SHORT_FLOAT_REPR
  macro which is always defined. gcc -Wundef emits a warning when
  using _PY_SHORT_FLOAT_REPR but the macro is not defined, if
  pycore_pymath.h include was forgotten.

bpo-46541: Discover the global strings. (gh-31346) 
Instead of manually enumerating the global strings in generate_global_objects.py, we extrapolate the list from usage of _Py_ID() and _Py_STR() in the source files.

This is partly inspired by gh-31261.

bpo-45490: Rename static inline functions (GH-31217) 
When a static inline function is wrapped by a macro which casts its
arguments to the expected type, there is no need that the function
has a different name than the macro. Use the same name for the macro
and the function to avoid confusion.

Rename _PyUnicode_get_wstr_length() to PyUnicode_WSTR_LENGTH().

Don't rename static inline _Py_NewRef() and _Py_XNewRef() functions,
since the C API exports Py_NewRef() and Py_XNewRef() functions as
regular functions. The name cannot be reused in this case.
