  WKDownloadProgress should write its progress as an xattr when unpublishing

Reviewed by Alexey Proskuryakov.

When unpublishing the NSProgress associated with a download, write an xattr on 
the progress file that reflects
the fraction of progress made on the download. (or -1 if a download of 
indeterminate length) This leaves a
record of the progress for outside observers to reflect if they encounter a 
file that represents a partially
completed download that happens to be paused, and therefore doesn't have a live 
NSProgress.

* Tools/TestWebKitAPI/Tests/WebKitCocoa/DownloadProgress.mm:
(-[DownloadProgressTestRunner init]):
(-[DownloadProgressTestRunner dealloc]):
    On creation/deallocation of the test runner, create and delete the file 
being used to publish progress.
    This file needs to actually exist for the purposes of the new test.
(-[DownloadProgressTestRunner progressURL]):
(TEST):
    DownloadProgress.ProgressExtendedAttributeSetAfterPartialDownloadStops: 
Start a download and pause it,
    partway through, then assert that the progress file has an extended 
attribute set that reflects the
    fraction of the progress made through the download.
