    Add option to stop updating X PRIMARY selection with the current visual 
region
    
    Vim user can select a region in visual mode and press the key `p` to
    replace the selected text.
    
    But in GUI Emacs, the selected text might not be replaced when:
    - `select-enable-primary` is `t`
    - Third plugins override `interprogram-paste-function` (xclip.el, for 
example)
    - Clipboard managers syncronise data between PRIMARY and CLIPBOARD selection
    
    It's because the visual commands automatically insert the content of 
visually
    selected region into X PRIMARY selection. But paste commands call the api
    `current-kill` which calls `interprogram-paste-function`.
    
    Value of `interprogram-paste-function` is `gui-selection-value` which
    might return CLIPBOARD or PRIMARY selection.
