This commit introduces the TypesIterator which is used to iterate over all types of a given spec. One notable user is "pwru" [1] which needs to iterate over all vmlinux BTF types to find functions which accept SKB as a param. The iterator is very similar to the existing InstructionIterator, as both export the Next() method and set the values and indices in the public fields.
