This adds reading of included service attribute 128bit UUID.
The limitation of this solution is that if several attr handle-range
pairs will be received, this will read first attribute UUID and then
start discovery from the the succeeding handle.

This makes it easier for application to handle all types of reads

Instead of destroy callback, call read_func with NULL data to

read is completed and parameters used for it are no longer needed.
Thanks to this application doesn't need to abuse user data destroy
callback for detecting if read has completed. Since destroy callback
is no longer needed it is removed.
Also note that bt_gatt_read doesn't take any user data parameter
and that destroy callback was acctually called with read parameters.
If application would require to pass user data along with parameters
it may use CONTAINER_OF macro along with bt_gatt_read_params.

This patch refactor reading of attribute values as a client.
Current MTU size is taken into account to determine if read
procedure has been completed or not.
For now, read procedure will be continued until whole is read,
or stopped by client.
Core Specification says that "The Read Blob Request is repeated
until the Read Blob Response’s Part Attribute Value parameter is
shorter than (ATT_MTU – 1)." (Vol 3, Part G 4.8.3)
Because application didn't know the current MTU value,
there was no way to determine if data received is complete.
