Reactive compute doesnt respect `always_update` #5125

When a reactive update is compute'd, its return value is compared to the current before invoking any watchers, irrespective of whether the reactive object is marked as always_update due to this logic here: https://github.com/Textualize/textual/blob/main/src/textual/reactive.py#L393-L396
