Matias N. Goldberg 4ce41495b1 Fix validation layer warnings 
1. Validation layers on Windows were complaining w/
VUID-VkSwapchainCreateInfoKHR-surface-01270 that we were not calling
vkGetPhysicalDeviceSurfaceSupportKHR before vkCreateSwapchainKHR.

2. Godot was only calling vkGetPhysicalDeviceSurfaceSupportKHR at
startup, but it should be doing this for every window w/ a new surface
it wants to create, not just the first one.
- In practice this will likely not make a difference. If
vkGetPhysicalDeviceSurfaceSupportKHR returns false after initialization,
there's nothing we can do about it and it is likely because something
else went terribly wrong, which is why the error message is worded like
that.
- This is mostly to shut up validation layers. Though technically,
the layers are right.

3. Do not call vkGetPhysicalDeviceSurfaceSupportKHR on queues we don't
even plan on ever using. We don't know how drivers will react to that
(e.g. they may preemptetively allocate resources to support presentation
on exotic queues, instead of just saying no). Just behave like every
other Vulkan app out there.
