feat: remove get_cells_by_lock_hash RPC and RPCs under indexer module

The following methods have been removed:
1. IndexLockHash
2. GetLockHashIndexStates
3. GetLiveCellsByLockHash
4. GetTransactionsByLockHash
5. DeindexLockHash
6. GetCellsByLockHash

BREAKING CHANGE: Remove RPCs under indexer module
