  Notify networking stack that download is media related
 https://bugs.webkit.org/show_bug.cgi?id=249569 rdar://103046339

Reviewed by Youenn Fablet.

Send a system notification when a networking operation is likely
going to be related to media playback.
For now the heuristic is rather primitive: if we have an active source buffer
linked to a media element we assume that all further networking operation in the
page is media related.
The notification is produced by the network process whenever a content process
has an active source buffers, and when all have been deleted.

The code was manually tested on a physical iPhone, however it fails on the simulator.
The api test will be added in a follow-up change (https://bugs.webkit.org/show_bug.cgi?id=250420)
