* lisp/tab-bar.el: Add a new tab on [mouse-1] instead of [down-mouse-1]

* lisp/tab-bar.el (tab-bar-mouse-down-1): Rename from
tab-bar-mouse-select-tab.  Ignore 'add-tab'.
(tab-bar-mouse-1): Rename from tab-bar-mouse-close-tab-from-button.
Use binding of 'add-tab'.
(tab-bar-map): Rebind [down-mouse-1] from tab-bar-mouse-select-tab to
tab-bar-mouse-down-1, and [mouse-1] from tab-bar-mouse-close-tab-from-button
to tab-bar-mouse-1 (bug#51246).
