Don't assign a `binding` to a `push_constant` buffer

Fixes #12

- This was a latent issue, but the previous commit brought it to the front.

- As indicated in #12, I don't allocate a descriptor-table slot to the block
  - Instead I allocate a `PushConstantBuffer`

- Unlike what #12 asks for, I don't use a different resource type for the contents of the block
  - Pretty much all the logic is easiest if these continue to be just plain `Uniform` data
