C++: Promote L2CAP_PSM, L2CAP_CID, .. to 'enum class'; Minor constexpr enhancements

'enum' -> 'enum class' w/ all bells and whistles: L2CAP_PSM, L2CAP_CID, AD_Type_Const

BTAddress.hpp: Add 'constexpr uint8_t number(..)'

constexpr:
- equality- and bit-operations on different types:
  EIRDataType, ManufactureSpecificData

- isEIRDataTypeSet(), setEIRDataTypeSet(), setAdapterSettingMaskBit()

HCIACLData Cleanup
- Use L2CAP_PSM and L2CAP_CID types
- Convenient queries if SMP or GATT type
- Add toString(..) w/ l2cap_data ptr

L2CAPComm: Use L2CAP_PSM and L2CAP_CID types
