[vk,swapchain] vsync: Changed Immediate fallback from (FIFO) to (Mailbox, then FIFO) (#3746)

Just discovered that stock adreno drivers on a730 had no Immediate VSync mode available, and it was falling back to FIFO, which causes a lot of response delay in Unity games.

But if someone chose Immediate, it prefers low latency above buffering, so Mailbox is his friend, and FIFO is his nemesis.

So i just changed Immediate to fall back to Mailbox first, and only if Mailbox is not available either it falls back to FIFO:

Immediate -> Mailbox -> FIFO;
Mailbox -> FIFO;
FIFO Relaxed -> FIFO.
