Allow excluding trusted programs from clipboard_control

[Danjoe4]

Terminal editors with a paste hotkey like neovim will produce this prompt for for users who are using their system clipboard for everything (e.g. vim.g.clipboard = 'osc52';).

Describe the solution you'd like
A config to allow specified trusted programs to ignore clipboard_control and read from the clipboard without a warning prompt.

Additional context

kitty cannot in general know what program is sending an OSC 52 request.
Think about running nvim over SSH. Thus such an option cannot be
implemented robustly. The correct solution for this issue is to allow
application specific passwords for clipboard permission, these can be
added to the extended clipboard protocol I invented, described here:
https://sw.kovidgoyal.net/kitty/clipboard/

If you can get buy in from nvim developers on supporting this protocol,
then I will be happy to add support for application specific passwords
to it.

The way it would work is the application would send a random uuid4 type
password string with its clipboard request along with a human friendly
application name. The terminal would display a confirmation which would
allow the user to:

1. Accept the request
2. Accept all future requests using that password for this tty
3. reject the request
4. reject all future requests using that password for this tty

this is secure and presents users with minimal inconvenience having to
confirm only once per nvim instance. Additionally, one can add pre-approved passwords to kitty.conf then any program using one of those pre-approved passwords will be automatically granted approval without a confirmation prompt.

Also, I should note that even in the local (non SSH) case, excluding a single program from the check means you effectively grant all programs running on that computer permission, since they can simply run the excluded program and use it to manipulate the clipboard. So there is no point having per program exclusions.
