Infers the concrete type of ResetTypes by their connections
There are 3 cases 1. An abstract reset driven by and/or driving only asynchronous resets will be inferred as asynchronous reset 1. An abstract reset driven by and/or driving both asynchronous and synchronous resets will error 1. Otherwise, the reset is inferred as synchronous (i.e. the abstract reset is only invalidated or is driven by or drives only synchronous resets)
This transform should be run before DedupModules so that similar Modules from generator languages like Chisel can infer differently
,This is a global inference because ports can be of type ResetType
