Move components for rendering locations to a separate file

[robertbrignull]

This PR achieves two goals:

• Converts code from "functions that happen to return react components" like renderLocation to actual react components that can have things like state and hooks.
• Pools together several similar and interdependent components for rendering locations.

This causes a slight increase in line count because we need to pass around more state as props rather than inheriting it from the environment. Arguably this is a benefit to long term readability and maintainability of the components by avoiding implicit coupling.

This PR is a potential stepping stone towards breaking up and modernising AlertTable. But this PR is not essential. I'm open to not grouping these functions into locations.tsx if this grouping of components doesn't make the code easier to understand.

Thanks for cleaning this up! I believe most of my comments are about things that were already there in the old components, but can be improved as part of this cleanup as well.
