[Security Solution] Specific Cypress executions for Entity Analytics team

[MadameSheema]

Summary

This PR is part of the effort we are making to have our cypres serverless tests ready for the second quality gate (QA environment - real serverless project and also part of the initial effort started by #153664.

With the introduced changes, we are creating specific Entity Analytics executions for both ESS and serverless with the aim of:

• To help to identify quickly the ownership of the tests in case of failure.
• To help to raise specific flakiness inside the tests of the team.

In this PR:

• We are creating different executions for ESS, serverless and the quality gate
• We are integrating everything with buildkite and also adding the new executions to the flaky test suite runner
• We are updating the readme
• We are removing the overall Security Solution execution.
