This PR makes a few changes to make sure that Root Signature Flags are always parsed validated and verified, this includes if you use a version that doesn't support flags. The logic already existed, this PR just makes sure it is always executed. Closes: [#161579](https://github.com/llvm/llvm-project/issues/161579) --------- Co-authored-by: joaosaffran <joao.saffran@microsoft.com>
