## Message

```
sema: Add union alignment resolution

- Add resolveUnionAlignment, to resolve a union's alignment only, without triggering layout resolution.
- Update resolveUnionLayout to cache size, alignment, and padding. abiSizeAdvanced and abiAlignmentAdvanced
  now use this information instead of computing it each time.

```
