dynamo: Count number of opcodes processes (#147149)
Summary:
This gives us a decent proxy for how big of a graph we functionally had to parse.
Note that this is a cummulative counter. If people feel strongly, I can either write into the dynamo_timed datasets with metrics contexts, or clear the counters / write a counter per frame id as well.
