[Torch FX] Changes to Support OpenVINO Quantizer (#3579)

### Changes

1. Add method to set ignored scope in Weight Compression algorithm. 

### Reason for changes

1. This is to allow the user of OpenVINO quantizer to set the ignored
scope from the instance without passing it in the quantizer
initialization.
