RFR: 8304089: Convert TraceDependencies to UL [v3]

[Coleen Phillimore]

> This change converts TraceDependencies to UL and removes the develop option. I think this provides further flexibility to add tags to only trace certain things in dependency analysis, as I did when trying to understand a PR for a deoptimization change.  For now, the messages are the same and the option is -Xlog:dependencies=debug.
> Tested with tier1-4
