bpf: btf: Remove unused btf_field_info_type enum

This enum was added and used in commit aa3496accc41 ("bpf: Refactor kptr_off_tab
into btf_record"). Later refactoring in commit db559117828d ("bpf: Consolidate
spin_lock, timer management into btf_record") resulted in the enum
values no longer being used anywhere.

Let's remove them.
