1. display: add display_flush …

   Introduces support for double-buffered/latched displays.
   Currently, every write has to be presented to the user immediately,
   which negates the advantage of latched displays to prevent frame tearing.

3. lvgl: call display_flush at the end of a frame …

   In frames with multiple writes (officially supported through
   `CONFIG_LV_Z_VDB_SIZE`) the display needs to be signalled that the
   current frame is over and the content should be displayed.
   This allows displays to present the UI without tearing artifacts.
