build(vim-patch): sound feature is n/a (#41257)

Vim core did not leverage it to override/customize bell/beep.
It wasn't used for custom sounds for system/user (autocmd) events.
It should be in-scope for GUI, unlike terminal, even as a plugin
by leveraging some internal option similar to `set guioptions+=!`.

No progress as of Vim 9.2 so I quit.
