Convert markstack to a slot visitor API
https://bugs.webkit.org/show_bug.cgi?id=53219

Move the MarkStack over to a slot based marking API.

In order to avoiding aliasing concerns there are two new types
that need to be used when holding on to JSValues and JSCell that
need to be marked: WriteBarrier and DeprecatedPtr. WriteBarrier
is expected to be used for any JSValue or Cell that's lifetime and
marking is controlled by another GC object. DeprecatedPtr is used
for any value that we need to rework ownership for.

The change over to this model has produced a large amount of
code changes, but they are mostly mechanical (forwarding JSGlobalData,
etc).
