[Bug Report][2.5.4] Icon inside v-menu activator is pointer even when clicks are disabled

[sbarfurth]

Environment

Vuetify Version: 2.5.4
Vue Version: 2.6.11
Browsers: Firefox 94.0
OS: Mac OS 10.15

Steps to reproduce

1. Create a menu with open-on-hover and :open-on-click: "false"
2. Place an icon inside the activator slot
3. Hover the icon

Expected Behavior

The icon should have the default cursor and not become a button. Clicking it should have no visible effect.

Actual Behavior

The icon is wrapped in a button and uses pointer as its cursor. Clicking the button gives it a background effect.

Other comments

As the icon does not provide any functionality when clicking it seems unintuitive that is appearing to the user as a clickable object. The menuable mixin appears to add a click handler regardless of props set on the menu.

The click listener was moved to menuable in 553a0d8c instead of staying in VMenu.
