HLSL uses a variety of named IR metadata and attributes to convey
additional information from the frontend to the backend. This document
tries to capture and document the named annotations to provide a
reference for future contributors.

HLSL doesn't have a C++ runtime that supports `atexit` registration. To
enable global destructors we instead rely on the `llvm.global_dtor`
mechanism.
This change disables `atexit` generation for HLSL and updates the HLSL
code generation to call global destructors on the exit from entry
functions.
Depends on D132977.

HLSL doesn't have a runtime loader model that supports global
construction by a loader or runtime initializer. To allow us to leverage
global constructors with minimal code generation impact we put calls to
the global constructors inside the generated entry function.

Along with the new documentation this also re-organizes the HLSL docs
to a subdirectory. The hope is to continue to expand this documentation
as the HLSL implementation advances.
