gh-92228: disable the compiler's 'small exit block inlining' optimization for blocks that have a line number (GH-94592) 
Inlining of code that corresponds to source code lines, can make it hard to distinguish later between code which is only reachable from except handlers, and that which is reachable in normal control flow. This caused problems with the debugger's jump feature.

This PR turns off the inlining optimisation for code which has line numbers. We still inline things like the implicit "return None".

gh-77560: Report possible errors in restoring builtins at finalization (GH-94255) 
Seems in the past the copy of builtins was not made in some scenarios,
and the error was silenced. Write it now to stderr, so we have a chance
to see it.

gh-74953: _PyThread_cond_after() uses _PyTime_t (#94056) 
pthread _PyThread_cond_after() implementation now uses the _PyTime_t
type to handle properly overflow: clamp to the maximum value.

Remove MICROSECONDS_TO_TIMESPEC() function.

gh-93937: PyOS_StdioReadline() uses PyConfig.legacy_windows_stdio (#94024) 
On Windows, PyOS_StdioReadline() now gets
PyConfig.legacy_windows_stdio from _PyOS_ReadlineTState, rather than
using the deprecated global Py_LegacyWindowsStdioFlag variable.

Fix also a compiler warning in Py_SetStandardStreamEncoding().

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.

using a mutex and a conditioinal variable.

* Add goto to avoid multiple indentation levels and exit quickly
* Use "while(1)" and make the control flow more obvious.
* PEP 7: Add braces around if blocks.

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
