StatsThread replaced by a Pipe:
...
* the thread was removed and its surrounding was cleaned up a bit
* ENamedThreads::StatsThread (and relatives) deprecated
* support for single-threaded execution looks a bit messy because it still have to be based on the old TaskGraph API until we convert the game thread to the new API (which will be one of the very last things)
* despite the direct usage of ENamedThreads::StatsThread from an external code is highly unlikely, to preserve backward compatiblity internally TaskGraph redirects all remaining stats tasks to StatsPipe

Refactored DECLARE_STAT macro to use EStatFlags instead of series of bool parameters. Added a mechanism to disable a external profiler and trace events for a specific stat. Disabled events for CPU stall stats by default.
...
Use `-verbosenamedevents` command line argument to allow all events (restore old behavior; implies `-statnamedevents`).
