Allow GattAttributes to have fixed length



Previously the concepts of initLength and lenth were clearly separated.

However, this was at the cost of registering all characteristics in the

SoftDevice as having variable length. Clearly, this is not the desired

behaviour. Therefore, an additional field '_hasVariableLen' is added to the

GattAttribute to address the problem. Also, the GattAttribute and

GattCharacteristic constructors have been modified to take a boolean that

sets '_hasVariableLen'.
