  [OpenMP][OMPT] Add OMPT callback for device data exchange 'Device-to-Device' (#81991)

Since there's no `ompt_target_data_transfer_tofrom_device` (within
ompt_target_data_op_t enum) or something other that conveys the meaning
of inter-device data exchange we decided to indicate a Device-to-Device
transfer by using: optype == ompt_target_data_transfer_from_device (=3)

Hence, a device transfer may be identified e.g. by checking for: (optype
== 3) &&
(src_device_num < omp_get_num_devices()) &&
(dest_device_num < omp_get_num_devices())

Fixes: #66478
