Rollup merge of #135383 - BoxyUwU:cov_tag_ptr, r=compiler-errors 
De-abstract tagged ptr and make it covariant

In #135272 I needed to use a tagged ptr in `hir::TyKind` in order to not regress hir type sizes. Unfortunately the existing `CopyTaggedPtr` abstraction is insufficient as it makes the `'hir` lifetime invariant.

I spent some time trying to keep existing functionality while making it covariant but in the end I realised that actually we dont use *any* of this code *anywhere* in rustc, so I've just removed everything and replaced it with a much less general abstraction that is suitable for what I need in #135272.

Idk if anyone has a preference for just keeping all the abstractions here in case anyone needs them in the future 🤷‍♀️

README.md

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.

Why Rust?

  • Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.

  • Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.

  • Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
