Clipboard support

[smerschjohann]

Fixes #6175

You can try with a dev build and a patched code-server cli script:

#!/usr/bin/env sh
#
# Copyright (c) Microsoft Corporation. All rights reserved.
#
# PATCH to DEV path
VSROOT=/home/coder/dev/code-server/lib/vscode
ROOT="$(dirname "$(dirname "$VSROOT")")"

APP_NAME="code-server"
VERSION="1.77.3"
COMMIT="704ed70d4fd1c6bd6342c436f1ede30d1cff4710"
EXEC_NAME="code-server"
CLI_SCRIPT="$VSROOT/out/server-cli.js"
"${NODE_EXEC_PATH:-$ROOT/lib/node}" "$CLI_SCRIPT" "$APP_NAME" "$VERSION" "$COMMIT" "$EXEC_NAME" "$@"

and use it like this:

echo -n my clipboard text | ./code-server --clipboard

If it makes like this, it would be cool to have it in code-server already.

Nonetheless, I think this addition makes sense in all vscode based applications, so I will try to create an issue and PR on the vscode repo.
Would be nice to read your thoughts.

As there is now an API to listen for terminal events, I will try to create an extension instead. This won't be as performant, but hopefully performant enough.
