Subject: Make `gfx::Renderer` a COM interface. (#1653)

* Make `gfx::Renderer` a COM interface.

This is a first step towards making the `gfx` library expose a COM compatible DLL interface. Remaining classes will come as separate PRs.

* Fixup project files

* Fix calling conventions

* Make gfx::create*Renderer() functions increase ref count by 1

* Make renderer createFunc return via out parameter
