Add RetryIfValue option to retry on given values

[totemcaf]

Sometimes want to retry if the computed values does not satisfy certain conditions. For example, you are waiting for some change to be applied to a persisted entity, so you want to retry until the entity read from persistence satisfy certain condition.

Example:

func (h *Handler) waitForApproval(ctx context.Context, id ids.Id) (*Entity, error) {
	return retry.DoWithData(func() (*Entity, error) {
		return h.reader.FindById(ctx, id)
        }, retry.RetryIfData(func (e *Entity) bool {
		return e.Status != StatusApproved // retry if the Status is not approved
       })
}

New type and func:

type RetryIfDataFunc[T any] func(T) bool

func RetryIfData[T any](f RetryIfDataFunc[T]) Option { // Option[T] ??
    // ...
}

It is challenging to handle type for Options to ensure consistency.

If you consider this to be useful (for me it is), I can provide a PR.
