chore(l1): memory enhancement - no transactional rocksdb + no cache

[rodrigo-o]

Motivation

This PR reduce memory by 40~50%

Description

This PR sits on top of #4821 and after different testing scenarios we came up with this cut in memory:

• reverts fix(l1): use transactional database with RocksDB #4599
• removes the rocksdb cache in options

The caveat is that it appears to be 50% slower, we need to double check it.

Here is a table comparision of 2 runs of this PR vs main:

Node Memory (RSS) & Host in images

Main	This PR #1	This PR #2
Snap time: 03:30	Snap time: 05:20	Snap time: 05:30
Mean: ~15.5GB & Max: ~22GB	Mean: ~8GB & Max: ~13GB	Mean: ~9.5GB & Max: ~15GB

This is an enhancement of ~40~50% in the Mean and ~30~40% in peaks, it appears to be a noticeable regression related to time ~50% slower, but we need more test to validate it wasn't an issue of the particular runs (variance for the runs is still high)
