N. Taylor Mullen 968e033e4b Make Block and Span cache Length.
- Part of caching length required the `Span`'s `ReplaceWith` method to propagate its changes to its parent so that it can propogate the change to invalidate all parent length caches.
- Added Span and Block tests to validate the interaction of caching.

N. Taylor Mullen 463e11b739 Make SyntaxTree mutations not leak.
- Prior to this when the partial parser would successfully parse a change we'd mutate the returned syntax tree so any data inquired about the tree would then be wrong. We now isolate mutations to copied versions of the syntax tree.
- Added copy tests to ensure that we were appropriately copying all the various syntax node types.
