chore(l1): reduce unnecessary docker builds and remove duplicate workflow executions in main

[rodrigo-o]

Motivation

We are re-building our docker image across the jobs/workflows multiple times, the idea is to remove as much of the duplicate executions as possible. At the same time, while merging to main we run duplicated jobs, the idea is to remove that duplication.

Description

This PR accomplish a couple of things:

• It creates a new make tasks for running hive without depending on the image build
• It generates a new job in the hive workflow to build the image once and then share it with every simulation
• Merges the assertoor stability check with hive to leverage the docker image already built
• Fix an issue were workflows were triggered two times in a row while merging to main (both merge_group and push rules were set)

Resolves #1008
Resolves #1041

Unfortunately, I wasn't able to share the Docker image across workflows, the only way to depend on other workflows for the triggering condition is pushing them first to the default branch, which I wasn't really convinced and preferred to just make it work. The caveat? both hive and assertoor now share the same workflow, this makes the naming a bit longer; apart from that the Docker build is also run in the CI (to let the L2/EVM teams still leverage the build as part of their checks\merge queue) timing shouldn't be an issue due to both run at the same time.

That said, we now removed 6 unnecessary builds from the run.
