gallium/tools: implement "high-level" overview mode option in dump scripts

As per the suggestion in #4609, implement mode/option -M/--method-only
which only prints call method names, for quick overview of what is
happening in the trace. The same option can be used with both
dump.py and tracediff.sh.
