Improve VIDiff: Detect binary files, Add logic for added/deleted VIs

[shivaCode-2]

Improvements in the existing VIDiff action:

1. Added logic to detect binary files by reading the last 8-12 bytes of the file instead of relying on the *.vi filter.
2. Added logic to generate reports for added/removed VIs as well.
3. Made the diff comment on the PR better: Now specifies whether the current VI is Added/Deleted/Modified.

Unrelated Change

1. Modify mirror-to-gitlab action such that its not triggered from forked repo PRs and only runs in base repo main context.
2. Modified VI Analyzer workflows to upload report as an artifact.
