[cfile] Improve the hash function of TypeEncodingInfo

In the original implementation, because `DataType` part and
`EncodingType` part will use the same bits, it is easy to
have hash collisions.

For example, the hash values of <UINT32=4, BIT_SHUFFLE=6>
and <INT32=5, PLAIN_ENCODING=1> are both equal to `100101`

This change also removed an unused member from `TypeEncodingTraits`
