rGfbb64aa69835: [BPF] extend BTF_KIND_FUNC to cover global, static and extern funcs
Summary
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

add a test case for extern function with arguments.

To handle cases (exposed when running linux kernel samples/bpf/sockex1) like below:

unsigned long long load_byte(void *skb, unsigned long long off) asm("llvm.bpf.load.byte");
unsigned long long test(void *skb) {
  return load_byte(skb, 10);
}

previous approach emits load_byte as load_byte function is in module function reference list.
But actually this function is not called so we should not emit extern func BTF for this.

Change to check all JAL instructions and emit extern func if necessary.
