Menu: handle many events with the menu - rather than menu items

Description

Alex suggested that we handle events in the menu widget rather than having them all on the menuItem widgets themselves.

We should replace the onClick and onMouseEnter/onMouseLeave functions on dijit.MenuItem? with corresponding functions on dijit.Menu

Summary: dijit.Menu: handle many events with the menu - rather than menu items → Menu: handle many events with the menu - rather than menu items

We can't remove MenuItem.onClick() because it would break backwards compatibility. At least not until 2.0.

It might be possible to have a callback on Menu in addition to the one on MenuItem, and that's what Menu.onItemClick() basically is, and also Menu.onExecute().

However, this is tricky to really have work. Menus can contain multiple subwidgets, not just MenuItem but also ColorPicker, !Calendar (except right now that breaks a11y)... I think it might even be possible to have a TooltipDialog but I'd need to test.

Anyway, this is something I thought about during the design of Menu and there's a reason it works the way it does now.

This should be easier w/the event delegation in dojo/on, except that it's broken for <tr>; I filed #14509 .

Some missing this.inherited() calls I noticed while working on event changes, refs #7111 !strict

In [27500]:

Move monitoring for mouse enter / mouse leave / ondijitclick from MenuItem to Menu. MenuItem is still monitoring onmouseenter/onmouseleave indirectly though, via _CssStateMixin.

Refs #7111 !strict.

In [27501]:

Disable monitoring of onmouseenter/onmouseleave/onmousedown events in MenuItem via _CssStateMixin. _CssStateMixin still knows about hover state, and sets appropriate CSS classes, because _MenuBase sets this.hovering for each MenuItem.

Start using :hover and :active pseudo-selectors except for IE6, where they aren't supported.

Fixes #7111 !strict.

In [27504]:

Do monitoring for widget hover/active state from a listenerd on <body>, rather than creating separate listeners for each widget. It's a bit like a "hover manager", similar to the focus manager in focus.js. Improves page-load performance. Refs #14568, #7111 !strict.

Reopening as reminder to change it to pass a function to on.selector() rather than ".dijitMenuItem", to eliminate dojo/query dependency. But waiting on answer to #14575 first.

If I end up using ".dijitMenuItem", then need to put dojo/query in the dependency list.

Avoid dojo/query dependency by using custom selector method, fixes #7111 !strict.
