Refactor attributes to reduce code duplication and improve maintainability.
* Add attribute base classes to provide common code.
* Add const where possible to functions and parameters.
* `NimBLECharacteristic::notify` no longer takes a `bool is_notification` parameter, instead `indicate()` should be called to send indications.
* `NimBLECharacteristic::indicate` now takes the same parameters as `notify`.
* `NimBLECharacteristicCallbacks` and `NimBLEDescriptorCallbacks` methods now take `const NimBLEConnInfo&` instead of non-const.
* `NimBLECharacteristic::onNotify` callback removed as unnecessary, the library does not call notify without app input.
* Add NimBLEUUID constructor that takes a reference to `ble_uuid_any_t`.
* `NimBLERemoteService::getCharacteristics` now returns a `const std::vector<NimBLERemoteCharacteristic*>&` instead of non-const `std::vector<NimBLERemoteCharacteristic*>*`
* `NimBLERemoteService::getValue` now returns `NimBLEAttValue` instead of `std::string`
* `NimBLEService::getCharacteristics` now returns a `const std::vector<NimBLECharacteristic*>&` instead of a copy of std::vector<NimBLECharacteristic *>.
* Replaces the use of std::list with a fixed array to track and manage created client instances.
* Removes: NimBLEDevice::getClientList
* Replaces: NimBLEDevice::getClientListSize with NimBLEDevice::getCreatedClientCount
* Make NimBLEConnInfo functions const.
* Update callback functions and update client to use new functions.
* Update examples.
* Update migration guide.

This replaces NimBLEAdvertisedDeviceCallbacks with NimBLEScanCallbacks and adds a onScanEnd callback.
The callback parameter for NimBLEScan::start has been removed and the blocking overload for NimBLEScan::start
has been replaced by an overload of NimBLEScan::getResults with the same parameters.
Change the callback functions that receive a ble_gap_conn_desc pointer to instead receive a NimBLEConnInfo reference.
* Add a reason parameter to the server disconnect callback.
* Remove connect and disconnect callback that do not receive info parameters.
* Remove onRead and onWrite Characteristic callbacks that do not receive info parameters.
* Add info parameter to Descriptor onWrite and onRead callbacks.
* Add details to migration guide.
Removes the unnecessary NimBLECharacteristicCallbacks::Status enum and callback parameter from NimBLECharacteristic::onStatus.
This was maintained for compatibility with the Arduino BLE library and is not necessary as the return code from the stack is also provided.
* Update examples/docs.
Changes all functions that accept a time parameter to use milliseconds instead of seconds.
* Adds duration input to NimBLEDevice::startAdvertising and NimBLEServer::startAdvertising.
