Mitch expressed a preference to not have `#ifdef`s in platform agnostic code, this change tries to accomodate this. I am not attached to the method this CL proposes, so if anyone has a suggestion, I am open. We move the platform specific member of the mutex into its own platform specific class that the main `Mutex` class inherits from. Functions are implemented in their respective platform specific compilation units. For Fuchsia, we use the sync APIs, as those are also the ones being used in Scudo.
