Bluetooth: TBS: Add support for long read with dirty bit

The TBS spec states that if a value is changed during a long read procedure, then the server shall reject read requests with offset != 0 with a specific TBS GATT error until the value has been read from the beginning again (i.e. with offset = 0). Signed-off-by: Emil Gydesen <[email protected]>
