TraceStrongly takes a WeakMember and strongifies it so that the
referenced objects is retained.
This is used in blink during tracing of some weak collections.

Cppgc exposes EphemeronPair that contains a WeakMember key and a Member

Tracing EphemeronPairs goes through TraceEphemeron that is exposed on

Adds a cross-thread reference for strongly and weakly retaining
objects on a thread other than the thread that owns the object.
The intended use of the reference is by setting it up on the
originating thread, holding the object alive from another thread, and
ultimately accessing the object again on the originating thread.
The reference has known caveats:
- It's unsafe to use when the heap may terminate;
- It's unsafe to transitively reach through the graph because of
compaction;

This adds support for injecting binding into contexts other than
main based on the context name (AKA isolated world name in Blink
terms). This would simplify a common use case for addBinding in
Puppeteer and other automation tools that use addBinding to expose
a back-channel for extension code running in an isolated world by
making bindings available to such code at an early stage and in a
race-free manner (currently, we can only inject a binding into
specific context after the creation of the context has been reported
to the client, which typically introduces a race with other evals
the client may be running in the context).

This change moves external pointers into a separate table and turns
external pointers in heap objects into indices into that table.
This CL implements one of two possible ownership models for the table
entries. With this one, every heap object owns its table entries, and
they are allocated when the owning object is allocated. As such, setting
external pointer fields does not require allocation of table entries. On
the other hand, table indices cannot be shared between multiple objects.
This CL does not yet implement freeing of external pointer table
entires. This will later happen by a table garbage collector.
