We are reusing the structures defined in `mcdxbc`, these structs are used to
serialize the Root Signature into the binary format. This is used in
`obj2yaml/yaml2obj` binary. Those require to be `uint32_t`, that is the value
that will be actually encoded in the binary and, most importantly,
`obj2yaml/yaml2obj` must be able to write invalid root signatures, and that is
not possible using an enum, due to a limitation of the yaml infrastructure.
