Pierre Goiffon a4f6f6e877 N°4368 Fix CORB blocking regression (#598)
Don't send X-Content-Type-Options HTTP header for certain WebPage impl to workaround CORB blocking
To disable globally this new behavior introduced in 9865bf07, set the `security.enable_header_xcontent_type_options` config parameter to false

Thanks @Molkobain for the review !
