🌳 SharedTree DDS Changes

Add IndependentTree API (#25785)

New IndependentTreeAlpha and IndependentTreeBeta APIs provide similar utility to the existing alpha `IndependentView` API, except providing access to the `ViewableTree`.

This allows for multiple views (in sequence, not concurrently) to be created to test things like schema upgrades and incompatible view schema much more easily (see example below). For IndependentTreeAlpha, this also provides access to exportVerbose and exportSimpleSchema from `ITreeAlpha`.

An example of how to use createIndependentTreeBeta to create multiple views to test a schema upgrade:

const tree = createIndependentTreeBeta();

const stagedConfig = new TreeViewConfiguration({
schema: SchemaFactoryAlpha.types([
SchemaFactory.number,
SchemaFactoryAlpha.staged(SchemaFactory.string),
]),
});
const afterConfig = new TreeViewConfigurationAlpha({
schema: [SchemaFactory.number, SchemaFactory.string],
});

// Initialize tree
{
const view = tree.viewWith(stagedConfig);
view.initialize(1);
view.dispose();
}

// Do schema upgrade
{
const view = tree.viewWith(afterConfig);
view.upgradeSchema();
view.root = "A";
view.dispose();
}

// Can still view tree with staged schema
{
const view = tree.viewWith(stagedConfig);
assert.equal(view.root, "A");
view.dispose();
}
