soc: espressif: set BLE HCI buffer defaults

Browse Source 
Set default values for BLE HCI buffer configuration that match
the ESP32 controller requirements:
- BT_BUF_ACL_RX_COUNT=24: Match controller's ACL buffer count
- BT_BUF_EVT_RX_COUNT=30: Match controller's event buffer count

Enable BT HCI node in device tree for all ESP32 SoCs that
support BLE.
