Auto merge of #83424 - cjgillot:noparam, r=lcnr

GenericParam does not need to be a HIR owner.

The special case is not required.

Universal impl traits design to regular generic parameters, and their content is owned by the enclosing item.

Existential (and opaque) impl traits generate their own enclosing item, and are collected through it.
