Support printing escape codes

[miv391]

Then you could use colors, for example:

print('\x1b[1;31mThis is bold red text')

See godotengine/godot#33541.

There is print_rich() (implemented by godotengine/godot#60675).

[Calinou]

For handling custom ANSI escape codes manually used in print() or print_rich(), godotengine/godot#90900 and godotengine/godot#92209 take care of it.
