feat: Support for inline attributes and aliasing (#131)

* Initial attribute changes. * Introduce ComAlias attribute with changes to name resolution strategy to support more complex aliasing scenario. * Update demo assembly 4 and include in the solution * Add unit tests to cover the enum alias using references to prove it still works across the interop boundary. * Remove an unused member that would be incorrect in a 32-bit build and modify the extension to reflect better the intention & scope of the extension and add some documentation on the extension ExtractInt32. * Address code style issues. * Add support for the Names option in the build task to mirror the CLI behavior.
