Move libs/apps code into libs/apps/runlocal subdirectory (#3933)

## Changes

The code in `libs/apps` was specific to the `apps run-local` command.

This moves it to `libs/apps/runlocal` to make `libs/apps` a collection
of packages rather than a single package.

## Why

Make space for other libraries under `libs/apps`.

## Tests

n/a
