Properly handle `SyntaxContext` of dummy spans in incr comp
Fixes #80336 Due to macro expansion, we may end up with spans with an invalid location and non-root `SyntaxContext`. This commits preserves the `SyntaxContext` of such spans in the incremental cache, and ensures that we always hash the `SyntaxContext` when computing the `Fingerprint` of a `Span` Previously, we would discard the `SyntaxContext` during serialization to the incremental cache, causing the span's `Fingerprint` to change across compilation sessions.
