HLSL Resource types need special annotations that the backend will use
to build out metadata and resource annotations that are required by
DirectX and Vulkan drivers in order to provide correct data bindings
for shader exeuction.
This patch adds some of the required data for unordered-access-views
(UAV) resource binding into the module flags. This data will evolve
over time to cover all the required use cases, but this should get
things started.
Depends on D130018.

The DXIL validator version option(/validator-version) decide the validator version when compile hlsl.
The format is major.minor like 1.0.
In normal case, the value of validator version should be got from DXIL validator. Before we got DXIL validator ready for llvm/main, DXIL validator version option is added first to set validator version.
It will affect code generation for DXIL, so it is treated as a code gen option.
A new member std::string DxilValidatorVersion is added to clang::CodeGenOptions.
Then CGHLSLRuntime is added to clang::CodeGenModule.
It is used to translate clang::CodeGenOptions::DxilValidatorVersion into a ModuleFlag under key "dx.valver" at end of clang code generation.
