[GNA] Fix KEY_EXEC_TARGET (cherry pick #7671) (#7701)

Browse Source 
* Use Gna2DeviceCreateForExport when GNA_EXEC_TARGET is != detected

* Update detected GNA device version field in GNA Device helper

   * Use EXEC instead of COMPILE TARGET to append
   CNN Legacy enforcement (GNA1)

* Apply review
