[PATCH V4 5/5] Enable BTF generation in the BPF backend

This patch changes the BPF GCC backend in order to use the DWARF debug hooks and therefore enables the user to generate BTF debugging information with -gbtf. Generating BTF is crucial when compiling BPF programs, since the CO-RE (compile-once, run-everwhere) mechanism used by the kernel BPF loader
