TPF is specifically the format used for shader model 4 and 5 shaders,
mostly as opposed to DXIL for shader model 6. I've been using
"VKD3D_SHADER_SOURCE_D3D_BYTECODE" for shader model 1-3 sources, and
"d3dbc" as the vkd3d-compiler string. We'd then potentially have the
following:

    "d3dbc" - Legacy Direct3D bytecode, no container.
    "dxbc-d3dbc" - Legacy Direct3D bytecode embedded in a DXBC container.
    "dxbc-tpf" - TPF (shader model 4/5) embedded in a DXBC container.
    "dxbc-dxil" - DXIL (shader model 6) embedded in a DXBC container.
