Rollup merge of #138776 - Zalathar:unexpand, r=oli-obk
coverage: Separate span-extraction from unexpansion

Historically, coverage instrumentation has relied on eagerly “unexpanding” MIR spans back to ancestor spans that have the same context as the function body, and lie within that body. Doing so makes several subsequent operations more straightforward.

In order to support expansion regions, we need to stop doing that, and handle layers of macro-expansion more explicitly. This PR takes a step in that direction, by deferring some of the unexpansion steps, and concentrating them in one place (`spans::extract_refined_covspans`).

Unexpansion still takes place as before, but these changes will make it easier to experiment with expansion-aware coverage instrumentation.
