Closes #3565, https://github.com/yt-dlp/yt-dlp/issues/3514#issuecomment-1105944364

On windows `conhost`, when `WINDOWS_VT_MODE` is enabled, `\n` is not
actually sent if the window is exactly the length of printed line,
and the line does not end with a white-space character. So the
line-break disappears when resizing the window.

Fixes #1863

Reverts "[utils] WebSocketsWrapper: Ignore warnings at websockets instantiation"

The warning should not be suppressed. We need to address it

This also fixes crash caused by moving asyncio to .compat.

Using https://github.com/PyCQA/isort

    isort -m VERTICAL_HANGING_INDENT --py 36 -l 80 --rr -n --tc .

Using https://github.com/asottile/pyupgrade

1. `__future__` imports and `coding: utf-8` were removed
2. Files were rewritten with `pyupgrade --py36-plus --keep-percent-format`
3. f-strings were cherry-picked from `pyupgrade --py36-plus`

Extractors are left untouched (except removing header) to avoid unnecessary merge conflicts
