refactor(etm): move ETM retention info from HAL to driver layer

Browse Source 
Move soc_etm_retention_desc_t type definition and soc_etm_retention_info
data from hal component to esp_hw_support component, following the
pattern of other peripheral retention data (e.g. MWDT).

- Create esp_private/etm_retention.h with type and extern declaration
- Create port/<target>/etm_retention.c for each target with retention data
- Remove hal/<target>/etm_periph.c and hal/include/hal/etm_periph.h
- Update esp_etm.c to include the new header
- Update CMakeLists.txt in both components
