Do it with statically defined menu items first, then work on #322 for asynchronously generated context menu items. |

Need to nail down the syntax (should be a Focus on just defining menu items for now, asynchronously building the menu using a callback can be done as a separate ticket after #322 is done. |

Fixes #322. Will be required for full completion of #321. Currently a little hard to test, but this should demonstrate it if you watch the JS debug logs on `WidgetHandler`. Run this Python code. - The `Normal` button should behave the same as latest dh.ui. - The `Nested` button will return a callable as the direct result of the callback function. This should allow us to do `const fn = await callable(args);` basically. It is not called, but there is a log from `WidgetHandler` after 5-10s that it was cleaned up. Or you can use the `Memory` tab in dev tools and click the broom icon to trigger a manual GC. - The `Double Nested` button will return and wrap an object containing a new callable. You can filter the browser logs for `WidgetUtils` and look for `callable ID result string` which won't have the parsed function, but will contain the object representing it as well as the other parts of the returned object. - The `Not serializable` button will basically do nothing except log an error in the Python console. The returned result will include that it was a serialization error to JS, but we do nothing with it. ```py from deephaven import ui @ui.component def my_comp(): on_press = ui.use_callback(lambda d: print(d), []) on_press_nested = ui.use_callback(lambda: print, []) on_press_double_nested = ui.use_callback(lambda: { "nestedFn": print, "some_val": 4 }, []) on_press_unserializable = ui.use_callback(lambda: set([1, 2, 3]), []) return [ ui.button("Normal", on_press=on_press), ui.button("Nested", on_press=on_press_nested), ui.button("Double Nested", on_press=on_press_double_nested), ui.button("Not Serializable", on_press=on_press_unserializable) ] c = my_comp() ```

Fixes #321 Here's an example with a context menu item on the row and a sub-menu action item on the header ```py from deephaven import empty_table, time_table, ui @ui.component def my_comp(): t = time_table("PT1S").update(["X=i", "Y=i"]) return ui.table( t, context_items=[{ "title": "Test", "action": lambda d: print(d)}], context_column_header_items=[ { "title": "Header", "actions": [{ "title": "Header-sub", "action": lambda d: print(d)}] } ] ) c = my_comp() ```

Dependent on #322
Once that's done, this should be fairly straightforward.
