Rollup merge of #146667 - calebzulawski:simd-mono-lane-limit, r=lcnr,RalfJung
Add an attribute to check the number of lanes in a SIMD vector after monomorphization

Allows std::simd to drop the `LaneCount<N>: SupportedLaneCount` trait and maintain good error messages.

Also, extends rust-lang/rust#145967 by including spans in layout errors for all ADTs.
