* lisp/tab-bar.el: Sort tab names by recency for tab switching (bug#38624)

* lisp/tab-bar.el (tab-bar--tabs-recent): New function with code
extracted from tab-bar--tab-index-recent.
(tab-bar-switch-to-tab): Use tab-bar--tabs-recent in interactive spec
to sort names of tabs by recency for default values of completing-read.
(tab-prefix-map): Bind RET to tab-bar-select-tab-by-name, and 'm' to tab-move.
