Make CI workflows fork-friendly

[wallentx]

Purpose:

This PR improves the CI experience for external contributors by ensuring that jobs can run successfully on forks. It resolves an issue where many CI jobs would get stuck in a pending state indefinitely because they were configured to use self-hosted runners that are only available in the chia-network/chia-blockchain repository. This change allows contributors to get timely and accurate feedback from the CI system.

This PR does not introduce a breaking change.

Current Behavior:

Currently, several CI jobs are configured to use specific self-hosted runners (e.g., [Linux, ARM64], macos-13-arm64, benchmark). When a contributor creates a pull request on their fork, these jobs are triggered but can never be assigned to a runner, as the required self-hosted runners do not exist in their forked repository. This causes the jobs to remain in a "pending" state forever, providing no feedback and cluttering the pull request's checks.

New Behavior:

The workflows have been updated with conditional logic based on the repository owner (github.repository_owner).

• If a workflow is running in the Chia-Network Organization, it will continue to use the specialized self-hosted runners as before.
• If the workflow is running on a fork, it will now use appropriate, publicly available GitHub-hosted runners (e.g., ubuntu-22.04-arm, macos-latest).

This ensures that all CI jobs can run to completion on forks, providing contributors with the feedback they need.

Testing Notes:
