[bgfx, bx, bimg] Add new ports

[Outurnate]

This is a resubmit of #7763 with some changes

• GENiE common logic has been moved to a common file
• tinystl includes the BSD license it's under with its include directory. This is a separate project, but it has the same license as bx

All the necessary changes were made. I took the time to update the commit refs from the upstream. I've also added a step to include the shader compiler tool which is necessary for projects using bgfx

There is a patch file included - I've submitted bkaradzic/bgfx#1958 to upstream this

@Outurnate You can click the Details link and view the log in Test Modified Port.

Linux error:

@JackBoosY upstream has declined to apply the patch. The CMake files generated by GENie don't link shaderc & friends to libdl. According to the maintainer of bgfx and vcpkg, CMake generation isn't supported (ref bgfx#1958)

Appreciate the pointer to the detailed logs. Since this change represents a total rewrite, I'll be closing this PR and resubmitting
