feat(disp) allow decouplig the disp_refr timer

Browse Source 
With this change after an lv_timer_del(disp->refr_timer); disp->refr_timer = NULL;
the user can call _lv_disp_refr_timer(NULL); anywhere to sync rendering with VSYNC or the TE signal.

lv_timer_handler() and _lv_disp_refr_timer() can not run at the same time.
