[Swift in WebKit] Apply SWIFT_RETURNED_AS_UNRETAINED_BY_DEFAULT to address
owner inference of FRT warning
https://bugs.webkit.org/show_bug.cgi?id=308456
rdar://170962301
Reviewed by Aditya Keerthi.
Currently, Swift clients of some C++ foreign reference types that are shared
references result in
a warning being emitted:
```
Cannot infer ownership of foreign reference value returned by 'get()'
```
This is because Swift is not able to detect itself if the value returned by a
function is retained
or unretained. Swift-Cxx interop addresses this by providing the
`SWIFT_RETURNED_AS_UNRETAINED_BY_DEFAULT`
annotation, which is applied to the relevant `SWIFT_SHARED_REFERENCE` types to
indicate that any
functions that return this type are unretained.
Fix by applying this annotation where needed.
