The continuous eroding of libbtf and the move to use libbpf APIs made
possible to ditch these aspects from libbtf.c and btf_elf, that is near
terminal death :-)

To move creation to pahole.c, i.e. outside the library, to the user,
then move the other methods still using the global variable.

I.e.:
$ rm -f vmlinux.btf ; pahole -j vmlinux.btf vmlinux && btfdiff vmlinux vmlinux.btf
Is much more robust in making sure we really generated new BTF from
the DWARF in a ELF file and that the detached BTF produces the same
output as the original DWARF.

For a vmlinux, the usual case, btf_encoder__encode() ends up being
called just from pahole, after processing all CUs, this looks like a
leftover from when Andrii made it support multiple CUs.

And this reduces the btf_encoder__encode_tag() signature, since we don't
have to pass this variable, as it is now in the 'encoder' parameter.
