Synthesize range responses if needed in WebCoreNSURLSession
https://bugs.webkit.org/show_bug.cgi?id=221072

Reviewed by Geoff Garen.

Source/WebCore:

When we make a media request with a Range HTTP header field and the server doesn't respond with a 206 with Content-Range header field,
until now we would just fail to play the video.  In order to successfully play these videos, I introduce the RangeResponseGenerator class,
which will receive the data for a request for such a video and feed the data into WebCoreNSURLSession as the requested ranges are received.
Seeking is problematic, but at least we will try our best to play the video.

I added API tests that try to play a video that didn't play before using a server that doesn't support range requests.  Manual verification is also necessary.
