  Log Message:
  -----------
  [HLSL] Add `[[hlsl::contained_type()]]` attribute (#108456)

Introducing a new HLSL resource type attribute `[[contained_type(T)]]`
which describes the "contained type" of a buffer or resource type.
Specifically, the attribute will be used on the resource handle in
templated buffer types like so:

template <typename T> struct RWBuffer {
  __hlsl_resource_t [[hlsl::contained_type(T)]] [[hlsl::resource_class(UAV)]] h;
};

Fixes #104855
