[webkit.UncountedLambdaCapturesChecker] Support [[clang::noescape]] on a constructor (#126869)
Added the support for annotating a constructor's argument with
[[clang::noescape]].
We explicitly ignore CXXConstructExpr which is visited as a part of
CallExpr so that construction of closures like Function,
CompletionHandler, etc... don't result in a warning.
