/// - imageAddress: A pointer to the start of the image. This value is _not_
/// equal to the value returned from `dlopen()`. On platforms that do not
/// support dynamic loading (and so do not have loadable images), this
/// argument is unspecified.
/// - typeMetadata: A type metadata pointer that can be bitcast to `Any.Type`.
/// - stop: A pointer to a boolean variable indicating whether type
/// enumeration should stop after the function returns. Set `*stop` to
/// `true` to stop type enumeration.
/// - context: An arbitrary pointer passed by the caller to
/// `swt_enumerateTypes()`.
