This issue handles the generation of root signature LLVM IR metadata from the parsed AST. Specifically, we will handle this for the `DescriptorTable` and `DescriptorTableClause`.
We will again follow the representation of a list of "root elements" following the defined [metadata representation](https://github.com/llvm/wg-hlsl/blob/main/proposals/0002-root-signature-in-clang.md#metadata-schema).
AC:
- [ ] Define `CGHLSLRuntime::addRootSignature` in `CGRuntime.h`
- [ ] Implement `CGHLSLRuntime::addRootSignature` in `CGRuntime.cpp`
- [ ] Implement metadata generation for `DescriptorTable` and `DescriptorTableClause` in `HLSLRootSignatures.[h|cpp]`
- [ ] Add usage of `addRootSignature` to `emitEntryFunction` in `CGRuntime.cpp`
- [ ] Add tests of generated metadata using `emit-llvm` in `CodeGenHLSL/RootSignatures.hlsl`
