Linus Groh 5832de62fe LibJS: Convert NativeFunction::{call,construct}() to ThrowCompletionOr
Both at the same time because many of them call construct() in call()
and I'm not keen on adding a bunch of temporary plumbing to turn
exceptions into throw completions.
Also changes the return value of construct() to Object* instead of Value
as it always needs to return an object; allowing an arbitrary Value is a
massive foot gun.
