btf_encoder: Adopt btf__encode_enum() as btf_encoder__add_enum() 

As it is just prep work to call libbpf's btf__add_enum for an
enumeration 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'.
