[BPF] extend BTF_KIND_FUNC to cover global, static and extern funcs

Browse Source 
Previously extern function is added as BTF_KIND_VAR. This does not work
well with existing BTF infrastructure as function expected to use
BTF_KIND_FUNC and BTF_KIND_FUNC_PROTO.

This patch added extern function to BTF_KIND_FUNC. The two bits 0:1
of btf_type.info are used to indicate what kind of function it is:
  0: static
  1: global
  2: extern
