Description
While developing code that you know isn't part of a higher order differentiation its really useful for compilation speed to turn off ForwardDiff's tagging, but that's not exposed here. Can we make it be? If we can agree on an API, I can implement it. I propose:
ForwardDiffBackend(tag=false) # default is true

Research direction
Start by locating the ForwardDiffBackend entry point and reading how its current options are passed to ForwardDiff. Compare that path with ForwardDiff's custom-tags and tag-checking documentation, then define and verify the proposed tag=false behavior while preserving the default tag=true behavior.
