Fix for some mutual exclusion errors

The "FSM active" part of the predicate for the IO was just coming from the wrong slice, should be the slice before not the slice after. The IO operation
happens after the slice that produces its predicate, and before the slice that consumes any output value (such as received data).

For a receive, the received data is available "live", not through a state element,
when the slice before it is active, supplying its predicate.

[codegen] Enhance cycle detection error messages in block elaboration.

The block elaboration process now provides more detailed information when a combinational cycle is detected. The error message includes a breakdown of the components involved in the cycle, such as FIFO instantiations and block instances, along with specific reasons for combinational paths within FIFOs and recommendations on how to break the cycle.

Refactor Verilog fuzzing to use a VerilogGenerator struct.

This change introduces a `VerilogGenerator` struct that encapsulates the XLS package, scheduling options, and codegen options. The fuzz domains now generate instances of `VerilogGenerator`, and the actual Verilog generation is performed by calling the `GenerateVerilog()` method on this struct. This allows fuzz tests to access the inputs (package and options) even when codegen fails, aiding in debugging.
