fix(node): support `tty.hasColors()` and `tty.getColorDepth()` (#24619)
This PR adds support for
[`tty.WriteStream.prototype.hasColors()`](https://nodejs.org/api/tty.html#writestreamhascolorscount-env)
and
[`tty.WriteStream.prototype.getColorDepth()`](https://nodejs.org/api/tty.html#writestreamgetcolordepthenv).
I couldn't find any usage on GitHub which passes parameters to it.
Therefore I've skipped adding support for the `env` parameter to keep
our snapshot size small.
Based on https://github.com/denoland/deno_terminal/pull/3
Fixes https://github.com/denoland/deno/issues/24616
