vulkaninfo: Correctly query per-surface queue support

The previous implementation did not differentiate when a single queue
supported a specific surface. It will now print 'true' if all surfaces
support presentation with a queue, 'false' if none, and otherwise prints
each surface type's support if they aren't uniform in value.

This makes the info regarding which queue supports presentation on a
surface much easier to validate the correctness of.
