ares: move generated sources out of ares.hpp (#1704)

Random fix from CMake work.

Precompiled headers under CMake are currently buggy and unreliable on
Windows, largely because the precompiled `<ares/ares.hpp>` header
includes `<ares/resource/resource.hpp>`, which is generated by
`sourcery` as part of the build process.

While sourcery will almost never meaningfully change the contents of
this `resource.hpp` file, Windows may insert its own line endings
depending on the user's environment, and despite enforcing uniform line
endings as part of our `.gitattributes` file, some compilers will throw
a fit about the precompiled header being modified from underneath it.

Since the `resource.hpp` file is simple, short, and not included in that
many places, we can just refactor it out of `<ares/ares.hpp>` without
issue, and precompiled headers will work again regardless of system line
ending convention or environment.

Tested to build locally on macOS; CI run definitely recommended.
