GATTNumbers: GATT_SERVICES ..: Use jau::make_darray<..>(..) to avoid copy-ctor; Disable its compilation and preserve resources.

GATT_SERVICES .. etc were merely created as a proof of concept to compile a complex static structure
representing detailed GATT services with its characteristics etc.

Its usage has been fixed to avoid std::initialize_list and copy-ctor.

One can enable its compilation and linkage
by defining `DIRECTBT_BUILDIN_GATT_SERVICE_CHARACTERISTIC_SPEC`.
