[AI-5800] Add quality gate to block PRs when size increase exceeds 1%

[lucia-sb]

What does this PR do?

Implements size quality gates in the repository. Only integrations and dependencies that are packaged with the Agent are considered for size changes. For now, the threshold is set to 1%, meaning that if a pull request introduces a size increase greater than this threshold, the PR will be blocked.

Motivation

The Datadog Agent has strict size constraints. This gate will help maintain strict size control and prevent unintentional growth over time.

Review checklist (to be filled by reviewers)

• [ ] Feature or bugfix MUST have appropriate tests (unit, integration, e2e)
• [ ] Add the qa/skip-qa label if the PR doesn't need to be tested during QA.
• [ ] If you need to backport this PR to another branch, you can add the backport/<branch-name> label to the PR and it will automatically open a backport PR once this one is merged
