[Snapping 2/5] Fix line-handle mid-point snapping (#2831)
Currently, only the end handles of the line tool snap. It should be all
of them.

Line handles work kind of weirdly at the moment: instead of just storing
the positions, we store full `TLHandle` objects complete with IDs,
`canSnap`/`canBind` properties, etc. Currently, all the handles get
written to the store with `canSnap: false`, when really it should be up
to the shape util to decide which handles are snappable.

This diff replaces the current handles map (from arbitrary ID to
`TLHandle`) with just the data we need: a map from index to x/y. The
extra information that the `Editor` needs for `TLHandle` is hydrated at
runtime (with `canSnap` set to `true` this time!)

Fixes TLD-2200

### Change Type

- [x] `major` — Breaking change


[^1]: publishes a `patch` release, for devDependencies use `internal`
[^2]: will not publish a new version

### Test Plan

1. Create a funky line shape on tldraw.com
2. Paste it into staging and make sure it comes across ok
3. Make some funky line shape in staging - make sure you use dragging,
mid-point creation, and shift-clicking

- [x] Unit Tests

### Release Notes

- Simplify the contents of `TLLineShape.props.handles`
