In my initial pass, I excluded several build phases that could plausibly be done in parallel to reduce risk. Now that the sandboxing and script fusing pieces have landed, we can begin opting more bits of the build into a state where the build planner can have more scheduling flexibility.

We had to revert the change landed in this bug (https://commits.webkit.org/314554@main) due to it breaking all of the builds.
