Specify initial serialization buffer capacity for Payloads

JFR shows a lot of re-allocations of the backing byte [] when
serializing CommitTransactionPayload. Specify a reasonable
initial buffer capacity (the default in ByteArrayOutputStream
is 32) to reduce re-allocations. This is also configurable via
the cfg file (default is 512).

Also did the same for the other smaller Payload classes like
PurgeTransactionPayload.
