  Add SPI for getting notification when WebsiteDataStore is removed in network process

rdar://problem/108634838

Reviewed by Chris Dumez.

There is a delay between WebsiteDataStore getting destroyed in UI process and network process stopping accessing files
that belong to the WebsiteDataStore. If UI process wants to operate on these files, it has to wait until network process
stops access, to avoid race or corruption. This patch introduces an SPI for client to know when network process finally
stops accessing the files.
