Dynamically load vulkan instead of statically link.
Make vk-bootstrap capable of loading the vulkan runtime and not need to link against the library. This improves the usability of vk-bootstrap since now you don't need the vulkan library on your system to build. This commit also changes how SystemInfo works so as to allow the dynamic vulkan loading.

To query the available layers and extensions, use the `get_system_info()` function of `vkb::InstanceBuilder` to get a `SystemInfo` struct. It contains a `is_layer_available()` and `is_extension_available()` function to check for a layer or extensions before enabling it. It also has booleans for if the validation layers are present and if the VK_EXT_debug_utils extension is available.
