Subject: Callable CPU code support (#1014)

* First pass support for compiling to a loaded shared library.

* Improve documentation for cpu target.

* Removed the SLANG_COMPILE_FLAG_LOAD_SHARED_LIBRARY flag.
Use the SLANG_HOST_CALLABLE code target
Document mechanism.

* Fix typo in cpp-resource.slang
In test code if the target is 'callable' we don't need to compile (indeed there is no source file).

* Small refactor using CommandLineCPPCompiler as base class to implement VisualStudioCPPCompiler and GCCCPPCompiler.

* Improvements around CPPCompiler.
Mechanism to know products produced.
Cleaning up products after execution.

* Fix multiple definition of 'SourceType'
