Hi @clementval 

This PR is pre-requisite for #140523
Have to do `omp_target_memcpy`  between two device ptrs, and to do that, need to access the base_addr and DataSizeInBytes from descriptor. 
I'm not aware of exisiting API regarding base_addr, If its already present, I will modify this PR accordingly.
