Simplify Windows write I/O around consoles on Windows 8+

Feature or enhancement

Proposal:

In bpo-11395 from 2011, Windows Python needed to check on every write if a write was to a tty / console object and limit the size of the write to avoid an OS error on write. With Windows 8 and above, the Windows subsystem has been updated and this check is no longer necessary. It is also not necessary to split the write into smaller pieces (which resulted in gh-110913 and gh-82052).

Based on PEP 11, the last Windows 8 support ended in 2023, so the isatty + limited write size is no longer needed on any currently supported Windows platform (Pipes are still limited write size).

That large writes work is tested in test_os, test_write_windows_console

Has this already been discussed elsewhere?

This is a minor feature, which does not need previous discussion elsewhere

Beginne mit der Abdeckung von Windows-Konsolenschreibvorgängen in test_os und test_write_windows_console und verfolge dann den zugehörigen Windows-Schreibpfad. Die Änderung ist abgeschlossen, wenn Konsolenschreibvorgänge unter unterstützten Windows-Versionen die veralteten Prüfungen oder das Aufteilen nicht mehr erfordern, die Beschränkungen für Pipe-Schreibvorgänge bestehen bleiben und die vorhandenen Tests für große Schreibvorgänge erfolgreich sind.
