Memory based eviction doesn't work with store as binary

The memory based eviction only currently works with byte[] for key and values.

We would like this also to support any key/value pair when store as binary is enabled. We would need to add a EntrySizeCalculator that would support MarshalledValue, the various MarshalledValueByteStream classes as well as all the types that MarshalledValue doesn't wrap (ie. Integer, Long etc.)
