refactor(gptimer): clean up SOC capabilities for GPTIMER and Timer Group

- Remove GPTIMER and TIMG related definitions from soc_caps_full.h files
- Move timer peripheral definitions to appropriate HAL layer files
- Update references across components to use proper HAL abstractions
- Consolidate timer group and GPTIMER capabilities organization
- Ensure consistent timer configuration across all ESP32 variants

This refactoring improves the separation of concerns between SOC
capabilities and HAL implementations for timer-related functionality.
