[util] Use FIFO_RELAXED present mode Earth Defense Force 5 (#2127)

The game constantly switches between SyncInterval 0 and 1, possibly in an attempt to implement adaptive Vsync, which causes performance issues because it forces us to recreate the Vulkan swap chain every couple of frames. Instead, enable the Vulkan equivalent of adaptive Vsync if possible.
