Zalathar 03de21ecc5 coverage: Build the expansion tree around SyntaxContext ...

The expansion tree was previously built around `ExpnId`, which was subtly
incorrect in cases where multiple distinct syntax contexts share the same
`outer_expn` ID. This can occur in the presence of nested macro expansions.

This change turns out to be fairly straightforward, because in all cases we
were obtaining `ExpnId` from `span.ctxt().outer_expn()` anyway, so we can just
remove the call to `.outer_expn()` and use the context instead.

As a result of this change, `context-mismatch-issue-147339.rs` no longer
triggers a context mismatch in `extract_refined_covspans`.
