Make Vulkan 1.1 Headers required

Browse Source 
Previously, the code tried to make it possible to use vk-bootstrap with
Vulkan 1.0 headers. This makes the code complicated and left several paths
completly untested. Making Vulkan 1.1 headers allows for simpler code.

Note: This does NOT make a Vulkan 1.1 capable driver required to use
vk-bootstrap. This only requires that the headers used to build
vk-bootstrap are 1.1 or above.

## Setting up `vk-bootstrap` ## Setting up `vk-bootstrap`
This library has no external dependencies beyond C++14, its standard library, and the Vulkan Headers. This library has no external dependencies beyond C++14, its standard library, and at least the 1.1 version of the Vulkan Headers.
Note: on Unix platforms, `vk-bootstrap` will require the dynamic linker in order to compile as the library doesn't link against `vulkan-1.dll`/`libvulkan.so` directly.
