Source/WebCore: Make DOMFileSystem selectively structure clonable so it can be the body of a web intent.

https://bugs.webkit.org/show_bug.cgi?id=88267

This functionality will allow FileSystem API objects to be dispatched to
web content in order to enable, for instance, an intent notifying web
content that a particular filesystem has been mounted by the local
system. The goal at this point is not to enable across-the-board
clonability, but just for handling the particular use case.

LayoutTests: Add filesystem regression test to check that the filesystem object is
not serializable as created by javascript.
