  [cocoa] Improve respecting X-Content-Type-Options: nosniff
https://bugs.webkit.org/show_bug.cgi?id=274242
rdar://109049343

Reviewed by Alex Christensen.

Respect the X-Content-Type-Options: nosniff header, instead of trying to guess
the best MIME type for the document based on the file extension.

Also convert isMainResourceLoad into an enum class, so it's consistent with isNoSniffSet.
