add flag to trace quantization passes

[shivadbhavsar]

Currently if we do something like: driver compile model.onnx --fp16

The quantize_fp16 pass will be run before compilation (meaning MIGRAPHX_TRACE_COMPILE will not be able to trace passes run here). Needed to use this trace for debugging so might be useful to merge in
