Add error handling on additional or missing data while decoding

[shuse2]

Description

During the decode, below check should be added assuming decoding is done in order of field number

• There is no skipped key to decode
• There is no additional bytes left after decoding

Only array of length zero should be allowed to be skipped as key

Motivation

We want to maintain behavior of https://github.com/LiskHQ/lisk-sdk/issues/6987 while more enforcing for the nested schemas to follow this protocol.
