Add auto wordwrap for StdoutProxy

[AnzhiZhang]

When I using Windows Terminal run cmd, run this code:

from prompt_toolkit.patch_stdout import patch_stdout

with patch_stdout():
	for i in range(100):
		print('a' * i)

If characters are too many longer than one line, extra part will be cut.

There is expected behavior

There is actual behavior

This bug will run only on Windows Terminal(sorry i am on chinese win):

It is not dependent of run cmd or Powershell in Terminal

In fact, I can get same error in both Windows Console Host and Windows Terminal (1.12.10334.0) on Windows 11 by using the script below

from prompt_toolkit.patch_stdout import patch_stdout

with patch_stdout():
    print('a' * 300)

(I'm also in a Chinese Win)
