Add new cds-access-api proxies

to significant overheads. This patch introduces proxies which are are
flat, i.e. have java.Object as their superclass, eliminating this
overhead.

The way we do this is we defined SerialForm interfaces which extend
Externalizable and define the serialization protocol in terms of default
methods. We then define a bunch of classes which are pure data holders
implementing individual SerialForms.

Also ensure messages properly implement cloneAsVersion() to propagate
the target version, now that it matters for them.

Finally audit use of java.io.Serial so that we do not import it -- it is
just pure overhead vs. using @java.io.Serial directly.

Externalizable -- the protocol to be easily implemented without a

Add Payload.serializedSize()

There is a rather big difference in payload sizing when we consider
how big an entry is: in-memory size can easily be "zero", which can
translate to a serialized size of hundreds of bytes. This difference
is problematic, as we use the former to estimate how many payloads
we can squeeze in AppendEntries and we compare that to the configured
payload limit. Even when there is some (32KiB by default) cushion, we
can end up blowing past the frame size.

Add Payload.serializedSize(), which should provide a semi-conservative
estimate of serialized size and use that to select the cut-off.

Also improve SimpleReplicatedLogEntry's estimates by performing a a
quick serialization operation -- which reduces potential waste for each
entry by 294 bytes, as our hard-coded estimate of 400 bytes was way too
conservative.

Make Payload Serializable
