Route Soroban TraceHook-based tracing into core trace-level tx logging

[graydon]

Description

Resolves #3980

This depends on stellar/rs-soroban-env#1324 and routes the output of a newly-surfaced tracing subsystem in that PR to the stellar-core trace-level tx logging partition. As with the observation code in soroban, it also reduces visual noise by only outputting captured trace-state diffs between lines, while a tx is running, outputting the full state at the tx beginning and ending.

I've tested this against testnet and it looks like so:
