gh-59705: Implement _thread.set_name() on Windows (#128675)

Browse source 
Implement set_name() with SetThreadDescription() and _get_name() with
GetThreadDescription(). If SetThreadDescription() or
GetThreadDescription() is not available in kernelbase.dll, delete the
method when the _thread module is imported.

Truncate the thread name to 32766 characters.
