Add CPU power management tools and dynamic frequency scaling

- Add cpu-power-control.sh: Script for managing CPU power limits and presets
- Add monitor-cpu-freq.sh: Real-time CPU frequency monitoring tool
- Add test-single-core-boost.sh: Tool for testing single-core boost frequencies
- Add BIOS-FIX.md: Documentation for BIOS configuration fix
- Update tlp.conf: Configure dynamic CPU frequency scaling (400MHz-4.2GHz on AC, 400MHz-2.2GHz on battery)
- Add Intel RAPL power limit controls for CPU power capping
- Enable dynamic frequency scaling with proper platform profiles
- Fix CPU frequency stuck at 1.6GHz issue (required BIOS SpeedStep disable)
- Configure balanced battery mode with 2.2GHz max for responsiveness
