AtlasEngine: Properly detect shader model 4 support (#13994)

Direct3D 10.0 and 10.1 only have optional support for shader model 4.
This commit fixes our assumption that it's always present by checking
`ComputeShaders_Plus_RawAndStructuredBuffers_Via_Shader_4_x` first.

Closes #13985

## Validation Steps Performed
* Set feature level to 10.1 via `dxcpl`
* `CheckFeatureSupport` is called and doesn't throw ✅
