6b9fe9e0 - [HLSL] Emit a version in the dx.rootsignatures metadata (#145113)

[HLSL] Emit a version in the dx.rootsignatures metadata (#145113) In #144957 the backend was updated to expect a version in the metadata, but since the frontend wasn't updated this breaks compilation. This is a somewhat temporary fix to that until #144813 lands.
