fix(ble_log): ensure BLE Log IRAM functions are placed in IRAM on ESP32C2

Browse Source 
On ESP32C2 with BT_CTRL_RUN_IN_FLASH_ONLY, the bt_default linker scheme
routes .iram1 sections to flash_text, causing BLE_LOG_IRAM_ATTR functions
to end up in flash instead of IRAM. Define a dedicated .ble_log_iram1
section for ESP32C2 and route it to iram0_bt_text unconditionally.


(cherry picked from commit a9b93ca0e5)
