b60022bb - [ThinLTO][NFC] Use a switch for ImportKind in exportToDot (#233610)

[ThinLTO][NFC] Use a switch for ImportKind in exportToDot (#233610) `ModuleSummaryIndex::exportToDot` used an if/else-if chain to choose the "definition" or "declaration" comment for each summary. `ImportKind` has only these two enumerators, so the else-if condition is always true when it is reached. Switch on the enum-typed `importType()` instead, without a `default` label, so that `-Wswitch` flags this code if a new `ImportKind` is added. With the previous code a new kind would silently get no comment. No new test, since this is NFC. The dot-dumper tests in llvm/test/ThinLTO/X86 exercise this function, and `dot-dumper.ll` is the only test that checks these comments. They pass, as does `check-llvm`. Assisted-by: Claude Code
