Consider removing uses of unsafeGlobalDynFlags for -dppr-debug

Currently various functions in Outputable use unsafeGlobalDynFlags to get the state of -dppr-debug. unsafeGlobalDynFlags is rather ugly, being a blob of global state spanning both module compilations and GHC API sessions. Consequently, we might consider removing it.

On the other hand, -dppr-debug is strictly a debug flag and removing unsafeGlobalDynFlags would likely require a lot more piping around of DynFlags. Consequently I suspect our current compromise of using unsafeGlobalDynFlags is the right solution. Nevertheless, I thought I would jot down the task.
