As we're now using a GitHub app to dispatch workflow requests from Drone to GHA, this patch updates the workflow runner script to handle app authentication.
In preparation for moving some builds from Drone to GHA, we need some
way for Drone to invoke a workflow in GHA and await the result. Handles
timeouts and workflow inputs as well.

We were inconsistent throughout the codebase and would sometimes
use the slices package and other times use our own equivalents
in api/.
This removes our versions in favor of the golang.org/x package that
does the same, which has the added benefit of reducing the surface
area of the public API module.
Note: despite existing uses of the slices package, for some reason
it didn't show up in go.mod or go.sum. Fixed that too.
