DetachPersistent() sets up PersistentHandles, but didn't properly set
up ordered_blocks_. So PersistentHandles::Contains failed for handles
that were detached from the main thread into PersistentHandles.

PersistentHandlesScope works similar to the DeferredHandleScope, but
returns PersistentHandles instead of DeferredHandles on Detach().
Since PersistentHandlesScope takes over filled blocks from the
main thread local handle, remove the block_size_ field and use
kHandleBlockSize instead. This way all blocks have exactly the same size.
