feat: Implement ATPIT Resolves rust-lang#16584 Note: This implementation only works for ATPIT, not for TAIT. The main hinderence that blocks the later is the defining sites of TAIT can be inner blocks like in; ```rust type X = impl Default; mod foo { fn bar() -> super::X { () } } ``` So, to figure out we are defining it or not, we should recursively probe for nested modules and bodies. For ATPIT, we can just look into current body because `error[E0401]: can't use 'Self' from outer item` prevent such nested structures; ```rust trait Foo { type Item; fn foo() -> Self::Item; } struct Bar; impl Foo for Bar { type Item = impl Default; fn foo() -> Self::Item { fn bar() -> Self::Item { ^^^^^^^^^^ | use of `Self` from outer item refer to the type directly here instead 5 } bar() } } ``` But this implementation does not checks for unification of same ATPIT between different bodies, monomorphization, nor layout for similar reason. (But these can be done with lazyness if we can utilize something like "mutation of interned value" with `db`. I coundn't find such thing but I would appreciate it if such thing exists and you could let me know 😅)

feat: Implement TAIT and fix ATPIT a bit Closes rust-lang#16296 (Commented on the issue) In rust-lang#16852, I implemented ATPIT, but as I didn't discern ATPIT and other non-assoc TAIT, I guess that it has been working for some TAITs. As the definining usage of TAIT requires it should be appear in the Def body's type(const blocks' type annotations or functions' signatures), this can be done in simlilar way with ATPIT And this PR also corrects some defining-usage resolution for ATPIT
