btf_encoder: Adopt btf__encode_struct() as btf_encoder__add_struct() 

As it is just prep work to call libbpf's btf__add_struct() for a
struct/union/class using pahole's data structures populated from another
format, normally DWARF.

So that we can eventually ditch the btf_encoder__verbose and
btf_gen_float globals, making them members of 'struct btf_encoder'.
