This pr fixes some inconsistencies in behaviour of how we handle `StaticSamplersOffset` with respect to DXC and `RootParameterOffset`. Namely: 1. Make codegen of `RTS0` always compute the `StaticSamplersOffset` regardless if there are any `StaticSampler`s. This is to be consistent and produce an identical `DXContainer` as DXC. 2. Make the `StaticSamplersOffset` and `RootParametersOffset` optional parameters in the yaml description. This means it will be used when it is specified (which was not necassarily the case before). 3. Enforce that the provided `StaticSamplersOffset` and `RootParametersOffset` in a yaml description match the computed value. For more context see: https://github.com/llvm/llvm-project/issues/155299. Description of existing test updates updates: - `CodeGen/DirectX/ContainerData`: Updated to codegen computed values (previously unspecified) - `llvm-objcopy/DXContainer`: Updated to `yaml2obj` computed values (previously unspecified) - `ObjectYAML/DXContainer`: Updated to `yaml2obj` computed values (previously incorrect) - `ObjectYAML/DXContainerYAMLTest`: Updated to `yaml2obj` computed values (previously incorrect) See newly added tests for testing of optional parameter functionality and `StaticSamplersOffset` computation.
