btf_encoder: Adopt btf__encode_struct_type() as btf_encoder__add_struct_type() 

As it is just prep work to call the various libbpf's btf__add*() for
structs/unions and its members 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'.
