Design looks good overall. I don't use any of this in V8, I just implement it from scratch (it's not much).

nit: I'd make an EmptyProvider type that documents its behavior

Closes #547
This basically removes the NowBuilder approach for a trait based approach.
In order to do this, it adds the HostClock, HostTimeZone, and HostHooks traits. I could see adding the HostHooks trait as potentially superfluous / controversial with the other two traits already present, but I thought it may provide a bit cleaner interface. Let me know what you think. Definitely willing to work shop this one a bit more if need be.
I did test this in Boa locally and there shouldn't be any regressions, which is nice.
