[SPIRV] Correctly map OpGenericCastToPtrExplicit builtins (#137189) 
The __spirv_GenericCastToPtrExplicit_To* builtins and its equivalent
OpenCL builtins (to_global, to_local and to_private) were mapped to
OpGenericCastToPtr instead of OpGenericCastToPtrExplicit.

The patch now uses OpGenericCastToPtrExplicit for these builtins.
