[ValueSerializer] Allow wire format versions beginning with 13 to be deserialized in non-legacy mode.

As of version 13, delegates do not need to worry about colliding tags with the
tags reserved by v8, since v8 inserts a "host object" prefix beforehand. Thus
the format is now suitable for more general use, without opting into the "legacy"
mode that had this caveat.

Now that the format has slightly fewer pitfalls, I'm hoping to allow this API to
be used without opting into "legacy wire format" mode. Ideally before node.js
and other folk start relying on enabling legacy mode.
