Rollup merge of #150650 - enthropy7:main, r=BoxyUwU

Forbid generic parameters in types of #[type_const] items

fixes rust-lang/rust#150614

we enforce the same restriction on `#[type_const]` const items that already exists for const generic parameters - when `generic_const_parameter_types` feature gate is not enabled, the type of a `#[type_const]` item cannot reference generic parameters.  implementation follows the same pattern used for const generic parameters. we check if the item has the `#[type_const]` attribute and if the feature gate is disabled, then we apply `RibKind::ConstParamTy` restrictions when visiting the type, which prevents the use of generic parameters.

check is added in three places:
- Free const items (`ItemKind::Const`)
- Trait associated consts (`AssocItemKind::Const` in traits)
- Impl associated consts (`AssocItemKind::Const` in impls)

added tests for new feature, hope i get this task right :>

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
