Auto merge of #57998 - niklasf:align-enum, r=nagisa
Allow #[repr(align(x))] on enums (#57996)

Tracking issue: #57996

Implements an extension of [RFC 1358](https://github.com/rust-lang/rfcs/blob/master/text/1358-repr-align.md) behind a feature flag (`repr_align_enum`). Originally introduced here for structs: #39999.

It seems like only HIR-level changes are required, since enums are already aware of their alignment (due to alignment of their limbs).
