feat(node): Update vercel ai integration attributes (#16721)

Make changes to the Vercel AI integration as per
https://www.notion.so/sentry/Agent-Monitoring-SDK-differences-21c8b10e4b5d80bcab51f72ae1418ea8

AI summary:

### Key Improvements:
1. **Eliminated duplicate attributes** - Tool call and prompt attributes
are now renamed instead of duplicated
2. **Added tool input/output support** - New `gen_ai.tool.input` and
`gen_ai.tool.output` attributes
3. **Auto-sets tool type** - Automatically adds `gen_ai.tool.type:
'function'` for tool calls
4. **Better OpenTelemetry compliance** - Cleaner attribute mapping
following semantic conventions

### Technical Changes:
- Uses `renameAttributeKey()` consistently instead of duplicating
attributes
- Removes old `ai.*` attributes after creating new `gen_ai.*` ones
