This is another approach for #97974 suggested by @oli-obk.

The plan with this is then to add the TyAlias variant into the rustc_type_ir TyKind enum.

I added the missing "explanation" for the ignored code block in the documentation.

🤣 this is missing like 112% of the context. The linked PR is a huge task it seems and I wanted @GuillaumeGomez to check if the problem is that we don't normalize in enough places or whether it's just the linked PR missing a normalization for the new type alias variant wherever we normalize projections. If this pr passes, then the linked PR should be trivial instead of adding normalization to a billion places. If this PR fails, then we can build tests that fail on master by doing the same thing as what this PR does just without a lang item and contained to a single test

Everything falls apart as soon as we run outside of bootstrap because it doesn't seem to be able to find the Identity lang item from what I can see.

Add missing normalization for union fields types

Overshadows rust-lang#106808.
From the experiment rust-lang#103985.

In short, it allows to use projections as a type for union's fields.
