This change is writing the in memory rootsignature representation into a global
variable in dxil, that is what DXContainerGlobals has done with PSV0, which I
reference to implement this.
The target branch is intentional, the targeted PR contains the logic
serialization and deserialization of Root Flags using obj2yaml. This change is
required to implement tests in this PR.
