vulkan: add .buf_elems to FFVulkanDescriptorSet

This enables users to specify a number that would be appended to
the buf_content string.
Saves users from needing to manually print to a string.

An earlier commit tried doing this via .elems, but it was
faulty, as this also incremented the total number of descriptors
in the descriptor set.
