[3.x] Enable ANSI escape code processing on Windows 10 and later

[Calinou]

3.x version of #44118.

This lets the engine and projects use the same color codes in the terminal on all platforms.

I tested this on Windows 10 (where it works) and on Windows 7 (where ANSI escape codes are printed as-is). Since Windows versions older than 10 are now EOL, this is probably acceptable, but feel free to improve on this in a future PR (e.g. by stripping ANSI escape codes).

Note that this PR does not include print_rich(), as it's difficult to backport. You can still print colored text to the terminal using the following approach:

var escape = PoolByteArray([0x1b]).get_string_from_ascii()
var code = "[1;32m"
print(escape + code + "Bold green text")

Since Windows versions older than 10 are now EOL,

Windows 8.1 support, and Windows 7 extended support, don't end until 2023. That said, Godot doesn't have to drop them at the same time as Microsoft (whether we do it earlier or later).

Windows 8.1 support, and Windows 7 extended support, don't end until 2023.

It's extended support for 8.1 and extended security updates (paid service for enterprise and embedded editions) for 7. Mainstream support ended a long time ago.
