This is a reland of https://crrev.com/c/v8/v8/+/1649257. The original change was reverted because it conflicted with a blink-side serialization tag. Make native errors serializable.

The slow-path emitted by the memory optimizer now checks if large object allocations were allowed before going ahead and allocating a large object. This is important because manual allocation folding in CSA must not be performed on a large object.

The current integration of crash keys into v8 got the dependencies wrong: it introduced into v8 a dependency on components and base. This change will allow moving the implementation into "gin" (via Platform's abstraction), which is ok to depend on components and base, while providing the default noop implementation for the embedders that don't care to collect crash keys.
