vulkan/instance: allow the requested api version to be larger than the supported

Browse source 
Since Vulkan 1.1, the requested API version is the maximum API version that the
application is expecting to use. It is also possible for individual devices
(backed by potentially different drivers) may support a higher or lower API
version than the instance.  Both cases (higher and lower) should be supported
and as such, it is not an error to request an API version that is larger than
the instance supported API version.
