Expose vsync interval with new cvar rpi_vsync_interval and support Vulkan vsync (#2061)
* Expose vsync interval with new cvar rpi_vsync_interval

On change, the rpi_vsync_interval is broadcasted to a new event on
the WindowNotificationBus and all swapchains are recreated with the
new vsync value.

* Add vsync interval support to the Vulkan RHI

Vsync intervals are not intrinsically supported using the Vulkan
swapchain extension. Instead, extra presents are enqueued for each
extra vblank requested past 1. Swapchain recreation is triggered
when transitioning to and from the FIFO presentation mode (when
rpi_vsync_interval transitions from and to 0 respectively).
