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.

This fills out the default constructor for RWBuffer to assign the
handle with the result of __builtin_hlsl_create_handle which we can
then treat as a pointer to the resource data through the mid-level of
the compiler.

This is pretty straightforward, it just adds a builtin to return a
pointer to a resource handle. This maps to a dx intrinsic.
The shape of this builtin and the underlying intrinsic will likely
shift a bit as this implementation becomes more feature complete, but
this is a good basis to get started.
Depends on D128569.

HLSL supports half type.
When enable-16bit-types is not set, half will be treated as float.
When enable-16bit-types is set, half will be treated like real 16bit float type and map to llvm half type.
Also change CXXABI to Microsoft to match dxc behavior.
The mangle name for half is "$f16@" when half is treat as native half type and "$halff@" when treat as float.
In AST, half is still half.
The special thing is done at clang codeGen, when NativeHalfType is false, half will translated into float.

Vector types in hlsl is using clang ext_vector_type.
Declaration of vector types is in builtin header hlsl.h.
hlsl.h will be included by default for hlsl shader.

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.
