Andrew Kelley 4bc88dd116 link: support exporting constant values without a Decl
The main motivating change here is to prevent the creation of a fake
Decl object by the frontend in order to `@export()` a value.

Instead, `link.updateDeclExports` is renamed to `link.updateExports` and
accepts a tagged union which can be either a Decl.Index or a
InternPool.Index.
