[WebKit] Swift build fails with "cannot infer ownership of foreign reference
value" errors
<https://bugs.webkit.org/show_bug.cgi?id=320315>
<rdar://183251187>
Unreviewed build fix.
Several WebKit implementation types are foreign reference types
(`SWIFT_SHARED_REFERENCE`), but do not declare how Swift should treat
the ownership of a returned value. A stricter Swift toolchain rejects
this: any function returning one of these types -- such as
`WTF::Ref<T>::ptr()`, `WebPageProxy::legacyMainFrameProcess()`, or
`WKWebView._impl()` -- fails to import because the compiler cannot infer
whether the result is passed retained (+1) or unretained (+0).
Mark each affected WebKit foreign reference type
`SWIFT_RETURNED_AS_UNRETAINED_BY_DEFAULT`. Like all normal WebKit
ref-counted types, they are returned +0, so a caller does not take
ownership of the returned reference. This mirrors the annotation
applied to the WebGPU types in bug 320306 (317935@main) and continues
the work in bug 308456 (309469@main) and bug 310101, which these WebKit
types were missing.
No new tests since this change is not directly testable.
