Auto merge of #162517 - khyperia:yeet-type-const, r=BoxyUwU

yeet `type const`



tracking issue: https://github.com/rust-lang/rust/issues/132980

zulip thread context (design decussion of future of gca): [#project-const-generics > talkies at last @ 💬](https://rust-lang.zulipchat.com/#narrow/channel/260443-project-const-generics/topic/talkies.20at.20last/near/620368825)

this PR does two things:

- implement `#[rustc_always_gca]` (bikeshed name thread: [#project-const-generics > #&#91;always_gca&#93; bikeshed](https://rust-lang.zulipchat.com/#narrow/channel/260443-project-const-generics/topic/.23.5Balways_gca.5D.20bikeshed/with/622249110) )
- remove `type const` syntax

it also migrates the test suite to the syntax introduced in https://github.com/rust-lang/rust/pull/162179 i.e. the new way to write `type const` is now `const ITEM: T = core::direct_const_arg!(V);` (ouch my hands, that took a while)

Website | Getting started | Learn | Documentation | Contributing

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).

Quick Start

Read “Installation” from The Book.

Installing from Source

If you really want to install from source (though this is not recommended), see INSTALL.md.

Getting Help

See https://www.rust-lang.org/community for a list of chat platforms and forums.

Contributing

See CONTRIBUTING.md.

For a detailed explanation of the compiler's architecture and how to begin contributing, see the rustc-dev-guide.
