9786: fix: Fix detection of macro file in inactive-code diag r=jonas-schievink a=jonas-schievink

Fixes https://github.com/rust-analyzer/rust-analyzer/issues/9753

`HirFileId::expansion_info` can return `None` for builtin macros or if there's an error in the macro call or definition, so add a `HirFileId::is_macro` method that checks the right thing.
