Add graphics+present queue type

[AnonN10]

Since it is not guaranteed by the standard for a graphics queue to support presentation and vkb::QueueType::graphics is used in tutorials for combined purposes of both rendering and presentation, for convenience reasons I'm suggesting to add a vkb::QueueType::graphics_and_present type that would perform an additional check under the hood and ensure its support.

I have a feeling it is pretty weird if every combination had it's own enum, apart from complicated naming and possible confusion.
I'd say defining operators on vkb::QueueType to OR the values together should be the better solution here. It would be much nicer from a readability perspective and would require the same under the hood changes anyway. If you agree, I'd be happy to open a PR.

enum class QueueType : uin32_t {}; // You know what goes here.

inline vkb::QueueType operator|(vkb::QueueType a, vkb::QueueType b) {
        return static_cast<vkb::QueueType>(
                static_cast<uint32_t>(a) | static_cast<uint32_t>(b));
}
