Introduce the ThreadContext

mbgl::Thread will keep a ThreadContext for each running instance
in a thread_local so we don't need to lookup a man in the Environment
every time we need some info about the current thread.

This patch is moving the ::currentlyOn check used on Debug build from
the Environment class to the ThreadContext.
