This commit introduces the following optimizations: 1. We return an empty array for text nodes in `getDirectives` because Angular does not support attaching logic to them. This optimization improves performance of `getDirectives` significantly because text nodes often result in expensive calls to `loadLContext` since we can't resolve it from a parent node. 1. `getDirectives` now calls `loadLContext` with second argument `false` so it doesn't throw an error. This brings another significant improvement because prevents the VM from deoptimizing calls. BREAKING CHANGE: Previously the `ng.getDirectives` function threw an error in case a given DOM node had no Angular context associated with it (for example if a function was called for a DOM element outside of an Angular app). This behavior was inconsistent with other debugging utilities under `ng` namespace, which handled this situation without raising an exception. Now calling the `ng.getDirectives` function for such DOM nodes would result in an empty array returned from that function. PR Close #41525
