fix(espidf): enable BLE 4.2 legacy APIs on BLE5-only SoCs 

C3/S3/C6 default to CONFIG_BT_BLE_50_FEATURES_SUPPORTED with 4.2 OFF, so
arduino-esp32's Bluedroid BLE library (esp_ble_gap_config_adv_data_raw,
esp_ble_gap_start_advertising) died at link with undefined references —
esp32c3-ble-advertise never compiled. Enabling 42+50 together matches
arduino-esp32's own per-target sdkconfigs; on classic ESP32 these flags
are already the Kconfig defaults. Found by the nightly gallery smoke.
