fix(debuginfo): disable overflow check for recursive non-enum types

Commit b10edb4 introduce an overflow check when generating debuginfo for expanding recursive types. While this check works correctly for enums, it can incorrectly prune valid debug information for structures.

For example see rust-lang/rust#143241 (https://github.com/rust-lang/rust/issues/143241#issuecomment-3073721477). Furthermore, for structures such check does not make sense, since structures with recursively expanding types simply will not compile (there is a `hir_analysis_recursive_generic_parameter` for that).
