Make always-visible '+' new tab button opt-in via tab_bar_show_new_tab_button

Browse source 
Default is 'no' to avoid forcing the button on all kitty users. When disabled,
the '+' indicator still appears during window drags as a drop target (existing
behaviour). Set to 'yes' to keep it permanently visible as a clickable button.

When set to :code:`yes`, a :code:`+` button is always shown at the end of the
tab bar as a clickable shortcut to open a new tab. When set to :code:`no`
(the default), the button is hidden at rest but still appears temporarily
while a window is being dragged, so it can be used as a drop target to open
the window in a new tab.
