fix vulkan vertex buffer indexing

Browse Source 
this was causing problems when i was specifying non-zero buffer slots in
`SDL_BindGPUVertexBuffers`, `SDL_GPUVertexAttribute` and
`SDL_GPUVertexBufferDescription`.

`firstSlot + 1` is simply copied over from metal and d3d12 backends.

(cherry picked from commit 512485869c)
