bpf: Add typecast to raw_tracepoints to help BTF generation
When pahole converts dwarf to btf it emits only used types. Wrap existing __bpf_trace_##template() function into btf_trace_##template typedef and use it in type cast to make gcc emits this type into dwarf. Then pahole will convert it to btf. The "btf_trace_" prefix will be used to identify BTF enabled raw tracepoints.
