Rollup merge of #137617 - BoxyUwU:generic_const_parameter_types, r=lcnr
Introduce `feature(generic_const_parameter_types)` Allows to define const generic parameters whose type depends on other generic parameters, e.g. `Foo<const N: usize, const ARR: [u8; N]>;` Wasn't going to implement for this for a while until we could implement it with `bad_inference.rs` resolved but apparently the project simd folks would like to be able to use this for some intrinsics and the inference issue isn't really a huge problem there aiui.
