feat(smart-contracts): lower contract size for PublicLock v15

[clemsos]

Description

This removes some code from PublicLock template so more features can be added without hitting the EVM contract size limit

Size: before : 23.956 / after: 22.636

Make some function private (avoid storing/copying full signature)

• schemaVersion (-0.032)
• set updateSchemaVersion internal (?)

Functions removed

• addLockManager (duplicate of hasRole(LOCK_MANAGER_ROLE, address)) and renounceLockManager (duplicate of renounceRole(LOCK_MANAGER_ROLE)) (-0.220)
• remove isApprovedForAll and setApprovalForAll(-0.477)
• refactor hooks addresses getters into a single hooks getter (-0.061)

Other cleanup

• remove previous migration code (-0.188)
• refactor hooks addresses checks (-0.349)

NOT doing:

• group fees into a single getter and a single setter (gas refund, transfer fee, cancel fee) (+0.063)
• refactor hooks addresses getters into a single hooks getter (-0.061)

Potential candidates for deletion

• function where feature can be recreated with workarounds : burn
• 'nice to have' / sad to delete functions : lendKey / unlendKey, mergeKeys
