On Android it's possible that the Activity/View must be restore. But,
before that patch, an new VkSurfaceKHR is created but never used and
that may lead to crash, in an attempt to destroy/use one invalid
surface.

Before this change, it was unclear who owned the platform specific
VkSurfaceKHR object, leading to a double-free in the error path for
devices with no Vulkan support. This change moves the ownership to the
platform specific code.
Add vk.EnumeratePhysicalDevices while here (refactor was part of
debugging of the double-free).

This change implements a Vulkan port for the two renderers, old and
compute. Run with GIORENDERER=forcecompute to test the compute renderer.
To shake out bugs faster, it is also made the default on systems that
support it. To disable Vulkan and force the use of OpenGL, use the
`novulkan` tag:
$ go run -tags novulkan gioui.org/example/kitchen
Don't forget to file an issue describing the issue that prompted the use
of the tag.
