Tweak WebCore::setMetadataURL function

https://bugs.webkit.org/show_bug.cgi?id=170786

Reviewed by Beth Dakin.

Source/WebCore:

Get rid of the "referrer" parameter, it isn't used. Make the remaining parameters const. Swap the
urlString and path parameters since that makes more sense. Use String instead of NSString in the call to WKSetMetadataURL.

* platform/FileSystem.cpp:
(WebCore::setMetadataURL): Deleted.
* platform/FileSystem.h:
* platform/mac/FileSystemMac.mm:
(WebCore::setMetadataURL):

Source/WebKit2:

Update for WebCore changes.

* UIProcess/Cocoa/WebViewImpl.mm:
(WebKit::WebViewImpl::namesOfPromisedFilesDroppedAtDestination):
