Rollup merge of #120564 - Zalathar:increment-site, r=oli-obk
coverage: Split out counter increment sites from BCB node/edge counters

This makes it possible for two nodes/edges in the coverage graph to share the same counter, without causing the instrumentor to inject unwanted duplicate counter-increment statements.
