Zap freed local and persistent handles similar to main thread handles.
As a drive-by change, fix the creation of local handles without
LocalHandleScope.

This CL allows LocalHandles to be dereferenced by the same thread that
created them, even if we have a DisallowHandleDereference scope.

This CL adds a linear search test in a DescriptorArray in a known flat
object in the background thread, while the main thread exercises the
same DescriptorArray.
Also sets the foundation for the follow-ups tests in background threads.

Add LocalHandleScope to allow for local handles in LocalHeaps
(background threads). This class is similar to HandleScope which still
needs to be used on the main thread. When performing a GC, the main
thread halts all background threads at a safepoint such that it can
safely iterate their roots.
