Capture all lifetimes for TAITs and impl trait in associated types

This reverts commit cb9467515b5a9b15aaa905683c6b4dd9e851056c, reversing changes made to 57781b24c54f9548722927ba88c343ff28da94ce. (This is only true for the tests, the change itself was done from scratch, as the compiler has diverged sufficiently for a revert to not make sense anymore).

This implements the lang team decision from this meeting: https://hackmd.io/sFaSIMJOQcuwCdnUvCxtuQ?view

r? `@cjgillot` on the impl
