Refactor health check probe result handling

Simplify the probe result collection logic by:
- Collecting all probe results upfront, regardless of healthChecker
- Checking for empty results based on FieldResults length
- Removing unnecessary tracking of empty probe fields
- Updating test expectations for multi-probe scenarios

This makes the code cleaner and maintains the fix for supporting
partial probe results with multi-probe configurations.
