Conforming to Equatable generates uncompilable Swift code

[abdulowork]

Reproduction

Conform to Equatable using:

extension MySwiftClass: Equatable {
    public static func ==(lhs: MySwiftClass, rhs: MySwiftClass) -> Bool {
        return false
    }
}

in Samples/SwiftJavaExtractFFMSampleApp/Sources/MySwiftLibrary/MySwiftClass.swift and run ./gradlew :Samples:SwiftJavaExtractFFMSampleApp:jextract -i.

The Swift compilation currently fails with:

102 | public func swiftjava_MySwiftLibrary_MySwiftClass_==_lhs_rhs(_ lhs: UnsafeRawPointer, _ rhs: UnsafeRawPointer) -> Bool {
    |                                                   `- error: expressions are not allowed at the top level

Oh that's a funny one, because the ==, should be a quick fix -- thank you
