[improvement](be) Add instance ID to hash join profiles

[HappenLee]

What problem does this PR solve?

Issue Number: None

Related PR: None

Problem Summary: Shuffle hash join build and probe operators run in separate pipelines, so their per-instance profiles are difficult to correlate. Add the fragment instance ID to both hash join build and probe custom profiles. Profiles with the same join node ID and InstanceID now identify the corresponding build/probe pair without relying on process-local hash table addresses.

Release note

None

  • git diff --check
• Behavior changed: Yes (hash join build and probe profiles include InstanceID)
