feat: process tagged logs

[Thunkar]

Closes: #9371 #9370 #9372

Blindly moves the logic in note_processor.ts to the simulator_oracle, so retrieved logs can be processed and injected in PXE's db. This approach has several problems:

• We have to trigger a process from an oracle, but the thing itself requires a simulator to call compute_note_hash_and_nullifier. This either implies moving lot of stuff into client_execution_context (namely, the key store), or a chicken and egg problem with simulator_oracle (we need a simulator in the oracle that is provided to a simulator). Right now a very ugly solution is adopted, instantiating a new simulator in place.
• Are deferred notes even necessary now? No, will be removed in Remove note processor in favor of new approach #9575
• Is there an alternative to passing the the dataStartIndexForTx all the way from the node to compute the note index? (this is not too bad IMO)
• Can the logic in the processor be simplified?
• Is there a better place to put this code that still allows us to initiate the process from aztec.nr?
