fix(drm): eliminate use of non-existent lv_api_map.h and enable smoke tests

[Johennes]

Description of the feature or fix

Compiling the DRM display driver currently fails because it uses a non-existent include.

This PR simply removes the include.

I also tried enabling compilation of both the DRM and FBDEV drivers on the CI in this PR.

Hi,
I resolved the conflict and check on mac. Now it's working. My changes are here. I can push to this PR if you allow me.

Thanks. I think I messed up because I couldn't get your branch to merge cleanly onto mine. But I've resolved the conflicts manually which hopefully should yield the same result.

I added guard to macros overrides in cmake. Confirmed it compiles. :)

Great, thank you! 👍

It's great that DRM is tested now at least by a build test.
