vulkan: remove instanceVersion class member

This is not actually needed. The api version specified when creating
the vulkan instance should be the highest api version that might
be used by the application, which can be higher than the supported
instance version. VMA can make use of vulkan 1.3 features so this
can be hardcoded to VK_API_VERSION_1_3.
