2555cdff - Remove `turbo_tasks::function` from `AssetContext::layer` (#80592)

Remove `turbo_tasks::function` from `AssetContext::layer` (#80592) ## Refactor `AssetContext.layer()` from a task function to a regular method ### Why? This eliminates a turbo task and a cell, but does not change invalidation behavior. I don't really anticipate a performance delta in any direction, but this this means in https://github.com/vercel/next.js/pull/80388 the new `LayerName` struct would not need to be a `turbo_tasks::value`
