- Add gptimer_priv.h with retention type definitions
- Create timer_periph.c files for 8 chips in esp_driver_gptimer
- Remove retention code from esp_hal_timg timer_periph.c (keep signals)
- 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.
