[Ada] Allow debugging finalization-related expanded code

[Pierre-Marie de Rodat]

exp_ch7.adb was missing calls to Set_Debug_Info_Needed on various
entities to allow debugging via -gnatD, now fixed.

Tested on x86_64-pc-linux-gnu, committed on trunk

gcc/ada/

        * exp_ch7.adb (Build_Finalization_Master, Build_Finalizer,
        Build_Object_Declarations, Make_Deep_Array_Body,
        Wrap_Transient_Expression): Call Set_Debug_Info_Needed on
        temporaries when Debug_Generated_Code is True.
