Extract the runner module into its own crate

This commit extracts the utiility runner module, used in the integration
tests into its own private crate.
The main motivation for this change is to enable sharing this
functionality between integration tests and the upcoming `javy-fuzz`
crate.

Additionally, this change promotes some dependencies to the
workspace level, namely:

- `tempfile`
- `uuid`
