gh-93937, C API: Move PyFrame_GetBack() to Python.h (#93938) 
Move the follow functions and type from frameobject.h to pyframe.h,
so the standard <Python.h> provide frame getter functions:

* PyFrame_Check()
* PyFrame_GetBack()
* PyFrame_GetBuiltins()
* PyFrame_GetGenerator()
* PyFrame_GetGlobals()
* PyFrame_GetLasti()
* PyFrame_GetLocals()
* PyFrame_Type

Remove #include "frameobject.h" from many C files. It's no longer
needed.

isinstance(x, type).

gh-89546: Clean up PyType_FromMetaclass (GH-93686) 
When changing PyType_FromMetaclass recently (GH-93012, GH-93466, GH-28748)
I found a bunch of opportunities to improve the code. Here they are.

gh-79512: Fixed names and __module__ value of weakref classes (GH-93719) 
Classes ReferenceType, ProxyType and CallableProxyType have now correct
atrtributes __module__, __name__ and __qualname__.
It makes them (types, not instances) pickleable.

gh-93741: Add private C API _PyImport_GetModuleAttrString() (GH-93742) 
It combines PyImport_ImportModule() and PyObject_GetAttrString()
and saves 4-6 lines of code on every use.

Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.

bpo-45383: Get metaclass from bases in PyType_From* (GH-28748) 
This checks the bases of of a type created using the FromSpec
API to inherit the bases metaclasses.  The metaclass's alloc
function will be called as is done in `tp_new` for classes
created in Python.

bpo-40514: Drop EXPERIMENTAL_ISOLATED_SUBINTERPRETERS (gh-93185) 
This was added for bpo-40514 (gh-84694) to test out a per-interpreter GIL. However, it has since proven unnecessary to keep the experiment in the repo. (It can be done as a branch in a fork like normal.) So here we are removing:

* the configure option
* the macro
* the code enabled by the macro

gh-60074: add new stable API function PyType_FromMetaclass (GH-93012) 
Added a new stable API function ``PyType_FromMetaclass``, which mirrors
the behavior of ``PyType_FromModuleAndSpec`` except that it takes an
additional metaclass argument. This is, e.g., useful for language
binding tools that need to store additional information in the type
object.

known to be valid.
