Catch previously missed violations in the `optional_enum_case_matching` rule when case expressions involved tuples. For example:
```swift
switch foo {
case (.bar↓?, .baz↓?): break
case (.bar↓?, _): break
case (_, .bar↓?): break
default: break
}
```

As was discussed #2737, I utilized the `indexsource` request to look up the operators and fetch the cursorInfo per operator. In the implementation I refrained from using `usr` to look up the operator because SourceKit [doesn't support](5add168042/tools/SourceKit/lib/SwiftLang/SwiftSourceDocInfo.cpp (L1799)) fetching cursorInfo by `usr` when it comes from C (but it can still be fetched by offset).
I also made [an alternative implementation](https://github.com/realm/SwiftLint/compare/master...biboran:fix-unused-imports-for-operators-alternative) which uses the `indexsource` request instead of the `editor.open`. It seems to work with the unit tests but I am not 100% sure it doesn't introduce a regression since there is no oss-check for analyzer rules.
I also updated [the example](https://github.com/biboran/synthax-bug-example) to better reflect the original issue in case you want to test the changes manually
