chore: separated deprecated modules into the contrib directory

[mmsqe]

Description

Problem:

• when new fields (such as max_supply) are added to proto files, we need api replacement (cosmossdk.io/api => ../api) to use the latest generated API files.
• modules like nft or crisis have been removed from api/cosmos, builds will fail due to missing packages.

Solution:

• separate deprecated modules into the contrib, distinct from api, to enable and unblock new proto changes without affecting legacy code.
