filelist generation for SystemVerilog

### Motivation

While refactoring the API for SystemVerilog we realized we do not have a filelist export for multiple file output.

rohd-bridge also generates a filelist.f, maybe worth considering? see:
https://github.com/intel/rohd-bridge/blob/5cba1f5c9df2562c54ce55279a73ee7d71b48cc6/lib/src/bridge_module.dart#L991

### Desired solution

Add an option for generating appopriate collateral like a filelist.

### Alternatives considered

### Additional details

_No response_

Start by reading the SystemVerilog API refactoring work and the linked rohd-bridge example in lib/src/bridge_module.dart around line 991. Trace where multiple-file output is produced and determine the appropriate option boundary; done means the option generates an appropriate filelist.f or equivalent collateral for SystemVerilog output.
