Rollup merge of #104614 - Nilstrieb:type-ascribe!, r=TaKO8Ki

Add `type_ascribe!` macro as placeholder syntax for type ascription

This makes it still possible to test the internal semantics of type ascription even once the `:`-syntax is removed from the parser. The macro now gets used in a bunch of UI tests that test the semantics and not syntax of type ascription.

I might have forgotten a few tests but this should hopefully be most of them. The remaining ones will certainly be found once type ascription is removed from the parser altogether.

Part of #101728
