core: do not check manifest size on deploy/update

Browse source 
Manifest will be a part of the state.Contract which will be checked on its
way to the storage. Tiny optimisation which allows not to serialize manifest
twice. Ref. https://github.com/nspcc-dev/neo-go/pull/3218#discussion_r1402374232.
