[Ada] CUDA: discover runtime types instead of hard-coding

Browse source 
gcc/ada/

	* exp_prag.adb (Get_Launch_Kernel_Arg_Type): New function.
	(Build_Shared_Memory_Declaration): Use
	Get_Launch_Kernel_Arg_Type.
	(Build_Stream_Declaration): Use Get_Launch_Kernel_Arg_Type.
	* rtsfind.ads: Remove RO_IC_Unsigned_Long_Long.
