Handle tab-bar clicks on a GPM-capable console.

* src/term.c (handle_one_term_event): Call tty_handle_tab_bar_click.

* src/xdisp.c (tty_handle_tab_bar_click): Force reset of up_modifier bit
from the event modifiers.

* lisp/tab-line.el (tab-line-tab-current): No need to use inverse-video
on console/xterm because the selected tab already uses inverse-video.
