Add Safari versions for api.CacheStorage.secure_context_required (#12507)

This PR adds real values for Safari (Desktop and iOS/iPadOS) for the `secure_context_required` member of the `CacheStorage` API.  By looking at the commit history (https://bugs.webkit.org/show_bug.cgi?id=175201, https://github.com/WebKit/WebKit/commit/25941073a6118fe00317ba6f14939409f1184560#diff-596ea61dc2e49a442d0317ce66a2ee9fb8fd4938a32ad74d4d97e1eb332dfbbd), it appears that Safari required a secure context right when this interface was implemented.
