shared/gatt-client: Make read/write cancelable The shared/gatt-client functions for initiating read/write procedures currently have no way to cancel them. The functions simple return a boolean result to indicate success/failure. This patch fixes this by returning a request id from these methods and adds the bt_gatt_cancel_* functions to cancel a request with one of these ids. bt_gatt_client internally manages its own set of request ids and maps them to the underlying ATT request id returned by bt_att_send to correctly cancel GATT procedures that span across multiple ATT protocol PDUs.
