<pre>
    The current DXC compiler library is an in process component. Desire has been expressed to have an out of process solution for compiling shaders. This solution should perform compilation in a reusable host process that is connected to by the c-style compiler library.

Assume there is a reliable library of code to support IPC (interprocess communication).

Requirements
* Design c-style entrypoints to compile a shader (no reflection support immediately)
* Add a new library to llvm-project build system that exposes the compile entrypoints
* Update clang executable to support being used as a host (reusable server process) and leverage IPC and perform compile requests issued via the new library
* Tests are implemented
* Documentation for the c-style entrypoints is written
