876: Fix support for d24unorm format r=kvark a=kvark

**Connections**
fixes kvark/vange-rs#121 on some platforms

**Description**
We used to associate `D24Plus` with internal `D24S8`. This results in assuming that it has both DEPTH + STENCIL. Creating a binding from it then fails with the `All` aspect, since you can't view both. This is unexpected, since the user creates `D24Plus` with just a single aspect.

**Testing**
None needed
