Add basic OpenTelemetry integration for signal metrics

The Scout OpenTelemetry integration uses OpenTelemetry SDK Autoconfigure
for initialization.

The other signals traces and logs are currently not tested and therefore
not activated/exported by default.

FocusManager: provide API to focus the next tabbable element

Usually, the browser automatically focuses the next tabbable element
in the DOM when the user presses the TAB key. This default behavior is
prevented in the smart field, because acceptInput() is asynchronous.
After the input is accepted, the focus is set to the next element
programmatically.

The previous implementation did not consider focus contexts, which
caused the focus to get "lost" when the last field on a dialog is a
smart field. To fix this, the corresponding logic in FocusContext is
exposed on the FocusManager and is now called by the SmartField.
