Michal Rostecki d102383d31 feat(aya-ebpf): BTF maps
Before this change, Aya supported only legacy BPF map definitions, which
are instances of the `bpf_map_def` struct and end up in the `maps` ELF
section. This change introduces BTF maps, with custom structs indicating
the metadata of the map, which end up in the `.maps` section.

Legacy maps are not supported by libbpf anymore and not even by the
kernel for newer types of maps like inode/task storage.

Add support of BTF maps in aya-ebpf under the `btf-maps` feature flag.

Usage of this feature requires emitting debug info for the eBPF crate
and passing the `--btf` flag to bpf-linker.
