Clarify the alignment of pOffsets passed to vkCmdBindVertexBuffers

[godlikepanos]

The documentation of vkCmdBindVertexBuffers doesn't mention something about the alignment of pOffsets. Not sure if the alignment requirements are mentioned in another section but I think it would be a good idea to have something as part of vkCmdBindVertexBuffers's documentation.

Alignment is validated after all vertex addressing logic has been applied, so it's too early to attempt validation at VBO bind time.

Right, true. I wonder if we can add some text that points to https://registry.khronos.org/vulkan/specs/1.1-extensions/html/vkspec.html#fxvertex-input-extraction for additional clarity.

@godlikepanos could you propose a PR adding a NOTE to that section, based on @HansKristian-Work's comment?

Sorry for the late update. I'll look into it.
