Use ANSI color codes on Windows as well

Windows' console supports ANSI escape sequences since Windows 10.
https://learn.microsoft.com/en-us/windows/console/console-virtual-terminal-sequences

PHP enables this by default since PHP 7.2.
https://www.php.net/manual/en/function.sapi-windows-vt100-support.php

PHP CodeSniffer special-cased Windows in this code in 2014
(bfd095d).
This is no longer needed today in 2024.

Note that the --colors option was already supported on Windows.
This only affects inline highlighting in error and debug messages.
