bpf: Refactor map->off_arr handling
Refactor map->off_arr handling into generic functions that can work on
their own without hardcoding map specific code. The btf_fields_offs
structure is now returned from btf_parse_field_offs, which can be reused
later for types in program BTF.
All functions like copy_map_value, zero_map_value call generic
underlying functions so that they can also be reused later for copying
to values allocated in programs which encode specific fields.
Later, some helper functions will also require access to this
btf_field_offs structure to be able to skip over special fields at
runtime.
