Add support for M3 series Apple Silicon chips

Adds hardware specifications for M3, M3 Pro, and M3 Max chips including:
- CPU and GPU power limits (TDP)
- Memory bandwidth specifications
- Enhanced hardware detection and monitoring support

This implements the M3 Max support from upstream PR and extends it
to cover the full M3 family for comprehensive Apple Silicon monitoring.
