aya-obj: add conversion u32 to enum type for prog, link, & attach type
Add conversion from u32 to program type, link type, and attach type. Additionally, remove duplicate match statement for u32 conversion to `BPF_MAP_TYPE_BLOOM_FILTER` & `BPF_MAP_TYPE_CGRP_STORAGE`. New error `InvalidTypeBinding<T>` is created to represent when a parsed/received value binding to a type is invalid. This is used in the new conversions added here, and also replaces `InvalidMapTypeError` in `TryFrom` for `bpf_map_type`.pull/1007/head
