(#95694) Optimize the implementation of AutoMap/AutoSet. Previously the `List` variant was backed by a `SmallVec` in inline mode, which needs at least 24 bytes of header (`len`, `cap`, `ptr` — all `usize`) even though the list never holds more than 32 elements. This replaces it with the `TinyVec` struct from turbo-tasks-backend which is now enhanced with support for an `inline` array. The length is a `NonZeroU8`, which reserves a niche the `AutoMap` enum folds its discriminant into — dropping `AutoMap`'s minimum size to 16 bytes. This in turn shrinks `TaskStorage` and the `LazyField` enum. Some inline structs in TaskStorage are increased in size so we keep the 128 byte footprint
