EntityIdUtils ignores realm and shard

[steven-sheehy]

Problem

The web3 module incorrectly uses just long entity num in places instead of using shard, realm and num.

Solution

• Change any method in EntityIdUtils to use shard and realm when encoding from an object to/from bytes or numerics
• Remove BitPackUtils
• Change EntityNum to internally use EntityId
• Investigate other areas like AllowanceId
