This is very much still work in progress and much more will change before the final 2.0.0
Some APIs have changed. New libraries have been added. LittleFS included.

* BLERemoteChar: fix descriptor 2902 write for characteristic notifications
When registering a notification on a characteristic, the 2902 descriptor
(CCCD) value is set to 1 (or 2 for indication).
According to the BLUETOOTH CORE SPECIFICATION Version 5.2, Revision Date
2019-12-31, section 4.12.3 "Write Characteristic Descriptors" (page 1588),
the characteristic descriptor write must expect a response.
Currently, the descriptor write is performed without expecting a reponse,
which prevents the notification to be functional with some BLE stacks.
This commit modify the write to expect the response.

* BLERemoteChar: forward GATT client event to characteristic descriptors
This commits prevents a permanent wait when calling BLERemoteDescriptor
readValue function, on the m_semaphoreReadDescrEvt semaphore.
ESP32 BLE stack calls to remote characteristic
- notification,
- value read
- value write
and remote characteristic descriptor
- value read
are asynchronous.
When such a call is performed by this library, a semaphore is taken prior
to the BLE stack read or write operation, and waited on after it.
Releasing the semaphore is done by the characteristic event handling
function (gattClientEventHandler), when the appropriate event is received.
However, the characteristic descriptor events are discarded, and the
value read semaphore is never released.
This commits forwards the GATT client events from the remote
characteristic down to their remote characteristic descriptor, and
implements their event handling.
Adding a semaphore for the remote characteristic descriptor value write
will be done in a separate commit.

* BLERemoteDescriptor: add semaphore to characteristic descriptor write
This adds a semaphore to characteristic descriptor value write, to mimic
the value read function, and to ensure completion of the operation before
we carry on.

* Updated BLERemoteCharacteristic to exposre esp_gatt_auth_req_t parameter for readValue and writeValue.
* Updated BLERemoteCharacteristic/Descriptor to expose a setAuth method to allow tweaking the authentication request type for that remotecharacteristic/descriptor without the need to add auth on each read/write.
* Replaced ARDUINO_VARIANT with const char
* Fixed missing return value
* Added quotes around defined value in macro (Issue #2193)
* Change logging from Error to Verbose when not found and default available
* Move Enter and Exit logging to Verbose Level
* Refactored LOG_X() into log_x()
