ADSP: Add support for assembler

In !7123 (merged) we added compiler information modules for the ADSP C and C++ compilers. Add one for the assembler too. We already identify the ADSP assembler since !1723 (merged).

Without those changes the assembler won't work because it will use -c to add sources and also the compiler will fail on linking the assembler file because it does not accept .obj as file suffix for object files.
