drivers/video: Refine the update region notification mechanism

Browse Source 
1.Expose the notification through fb_vtable_s::updatearea
2.Incorporate old nx_notify_rectangle into the new updatearea callback
3.Migrate the calle of nx_notify_rectangle to fb_vtable_s::updatearea

* Name: nx_notify_rectangle
*
* Description:
* When CONFIG_NX_UPDATE=y, then the graphics system will callout to
* inform some external module that the display has been updated. This
* would be useful in a couple for cases.
*
* - When a serial LCD is used, but a framebuffer is used to access the
* LCD. In this case, the update callout can be used to refresh the
* affected region of the display.
*
* - When VNC is enabled. This is case, this callout is necessary to
* update the remote frame buffer to match the local framebuffer.
*
* When this feature is enabled, some external logic must provide this
* interface. This is the function that will handle the notification. It
* receives the rectangular region that was updated on the provided plane.
