Changed to use native AbortController and AbortSignal from Node.js, instead of the one from node-abort-controller. This is possible now that the minimum supported Node.js version of the project is 16.

Note that their interfaces are very slightly different, but typically not in a way that matters to consumers. If you see any typescript errors as a direct result from this, they are compatible with each other in the ways that we interact with them, and should be possible to type-cast across without ill effects.
