bpftool: Implement btfgen_get_btf()
The last part of the BTFGen algorithm is to create a new BTF object with
all the types that were recorded in the previous steps.
This function performs two different steps:
1. Add the types to the new BTF object by using btf__add_type(). Some
special logic around struct and unions is implemented to only add the
members that are really used in the field-based relocations. The type
ID on the new and old BTF objects is stored on a map.
2. Fix all the type IDs on the new BTF object by using the IDs saved in
the previous step.
