fix(cdk/tree): resolve maximum call stack error (#29754)

The CDK tree was calling `ChangeDetectorRef.detectChanges` recursively for each node in the tree which was overflowing the call stack with some larger trees.

These changes resolve the issue by only calling `detectChanges` on the root.

Fixes #29733.
