[InferResets] Print field/signal names in diagnostic 8 months ago

AI Summary: The `InferResets` pass in CIRCT's FIRRTL dialect currently produces diagnostic messages that lack specific field, signal, or port names, making debugging difficult, especially with complex bundles or multiple resets. The proposed solution is to implement a `guessName(FieldRef fieldRef)` function that traverses the FIRRTL IR to construct a hierarchical name for the field, which can then be included in the diagnostic output to provide more helpful context to the user.

Complexity: 3/5
