Add option to either use system clipboard or vim clipboard (#7936)

Release Notes:

- vim: Added a setting to control default clipboard behaviour. `{"vim":
{"use_system_clipboard": "never"}}` disables writing to the clipboard.
`"on_yank"` writes to the system clipboard only on yank, and `"always"`
preserves the current behavior. ([#4390
](https://github.com/zed-industries/zed/issues/4390))
