Vulkan PhysicalDevice + Device Initialization + Report Accurate Version

Vulkan Device initialization is handled now, it supports required extensions but support for optional extensions/features/properties will come in later when we require those. In addition, we now correctly report the version of Skyline to Vulkan which can be accessed from debugging tools. 

There's also a minor change regarding the search pattern for `SkylineLibraries` which now only searches in headers of libraries and it also explicitly excludes the redundant `vulkan.hpp` from the `Vulkan-Headers` repository.
