vulkan: Respect VK_KHR_portability_subset vertex stride alignment (#4419)

Browse source 
* vulkan: Respect VK_KHR_portability_subset vertex stride alignment

We were hardcoding alignment to 4, but by specs it can be any values that
is a power of 2.

This also enable VK_KHR_portability_subset if present as per specs
requirements.

* address gdkchan's comment

* Make NeedsVertexBufferAlignment internal
