btf: expose get_btf_id
Expose the function get_btf_id, so that it may be used by the BPF
backend. This enables the BPF CO-RE machinery in the BPF backend to
lookup BTF type IDs, in order to create CO-RE relocation records.
A prototype is added in ctfc.h
gcc/ChangeLog:
* btfout.c (get_btf_id): Function is no longer static.
* ctfc.h: Expose it here.
