Add thread naming support on platforms that support it.

As a client of grpc I want to be aware of which threads are being
created by grpc, and giving them recognizable names makes it significantly
easier to diagnose what is going on in my programs.
This provides thread names for macOS and Linux. Adding support for other
platforms should be easy for platform specialists.
