core, core/rawdb, eth/sync: no tx indexing during snap sync (#28703)

Browse Source 
This change simplifies the logic for indexing transactions and enhances the UX when transaction is not found by returning more information to users.

Transaction indexing is now considered as a part of the initial sync, and `eth.syncing` will thus be `true` if transaction indexing is not yet finished. API consumers can use the syncing status to determine if the node is ready to serve users.
