HashWire is non-binary (text) wire which leads to object allocation, CPU usage

[alamar]

We have HashWire used to calculate hash codes of SelfDescribingMarshallable, which is a text wire (it does not override isBinary() to return true). Which leads to easy 6-7x CPU usage as well as object allocations.

I guess we can't change it since it will affect existing objects' hash codes, which could be stored by our users. Maybe we can introduce a system property to make it use the binary form, which we will then make the default (in 2.23 or 3.X?)

I personally think it is OK to change the hash value now, in x.22

I suggest doing that by default in 2.24 @minborg Should I reassign it to myself?

Please do @alamar
