  1. [Arc] Partially enable reset/enable detection 

    Enable the `InferStateProperties` pass in the arcilator pipeline and
make its enable and reset signal detection individually controllable.
The enable portion is already supported by the rest of the arcilator
pipeline and can produce 20%-35% speedup on the cores in arc-tests.Turn
on enable detection by default.

The reset portion is not fully supported yet and causes the simulation
to misbehave. It is disabled by default.

As a minor refactoring this removes the `constructor` field from the
pass definition, such that the constructor and plumbing for options gets
generated automatically. As a side effect, the constructor is now called
`arc::createInferStateProperties` instead of the previous
`arc::createInferStatePropertiesPass`. (Thanks @uenoku for the pointer.)

Shoutout to @maerhart and @TaoBi22 for this fantastic pass!
