indexer: stop indexing tx_input_objects and tx_changed_objects

[amnn]

Description

Stop indexing these tables in favour of tx_affected_objects. This change cannot land without GraphQL first being updated to avoid reading these tables (otherwise its tests will fail as these fields are no longer indexed), but the PR is being put out early for experimentation.

Test plan

sui$ cargo nextest run -p sui-indexer
