[Fleet] Enhancements on package install state machine

[criamico]

Phase 1 of https://github.com/elastic/kibana/issues/169147

Follow up of https://github.com/elastic/kibana/issues/175592. There were some left over items that were not implemented in the first PR.

For each state transition:

• [ ] Implement and check initial conditions that need to be verified prior to execute each state, if needed
• [ ] Implement retries and recovery steps to execute when the state failed, if needed
• [ ] Introduce a mechanism to avoid repeating the steps that were already successful
• [ ] Introduce a flag that allows to do the whole reinstall from scratch (we could reuse force for that)
• [ ] Add telemetry and logging for monitoring the new functionality - define the structure for the telemetry data

Currently the new functionality under enablePackagesStateMachine is only used in install by registry. Enable it in the other install flows

• [ ] Install by upload
• [ ] Install custom integrations
