Store-level "operation end" event (#3748)
This adds a store-level "operation end" event which fires at the end of
atomic operations. It includes some other changes too:

- The `SideEffectManager` now lives in & is a property of the store as
`StoreSideEffects`. One benefit to this is that instead of overriding
methods on the store to register side effects (meaning the store can
only ever be used in one place) the store now calls directly into the
side effect manager, which is responsible for dealing with any other
callbacks
- The history manager's "batch complete" event is gone, in favour of
this new event. We were using the batch complete event for only one
thing, calling `onChildrenChange` - which meant it wasn't getting called
for undo/redo events, which aren't part of a batch. `onChildrenChange`
is now called after each atomic store operation affecting children.

I've also added a rough pin example which shows (kinda messily) how you
might use the operation complete handler to traverse a graph of bindings
and resolve constraints between them.

### Change Type

- [x] `sdk` — Changes the tldraw SDK
- [x] `feature` — New feature

### Release Notes

#### Breaking changes
`editor.registerBatchCompleteHandler` has been replaced with
`editor.registerOperationCompleteHandler`
