Fixes #?

Context

Add an internal flag that causes Gradle to attempt to load and run the work graph from cache in the same Gradle invocation that it is stored in. This behaviour is currently behind a flag because there are several things broken when enabled, which will be fixed over several PRs. The basic behaviour seems to work, however.
