Pack all the information and prepare for upload

[agoldis]

• Add run context (spec, test, attempt?) in meta field
• Check how multiple attempts are working
• Pack everything together on a test (or event attempt level)
• Think of it as if the file would be uploaded to cloud / stored as a CI artifact
• Provide a way to fetch the file

Think of how would you integrate it with cypress-cloud and upload to a dashboard

@vCaisim seems like callback to install fn can work
