These are throttled/debounced so the handlers are sometimes called after the
component has been destroyed.

Because the position of the popover depends on the size of its content.

Part of task-2270731

X-original-commit: 3066a946ef1ca0973503207d0486515798168fa2

Close can now be requested by children (slot content) with the event
`o-popover-close`. This feature is necessary if we want a "close" button inside
the popover itself, which is the case for mail.activity "Mark Done".

Clicking on the popover target now acts as a toggle, which is also a feature
that was expected from the previous popover implementation.

Add a specific class (`o_is_open`) when the popover is displayed to be able to
style its target depending on whether it is displayed or not.

Ensure computed position is whole number of pixels to prevent flicker issue on
Firefox.

Remove forced width to let the component grow with its content.

Add appropriate z-index to prevent overlap issue with the rest of our interface.

Using bootstrap popover with owl is possible, but with a lot of
friction.

This commit adds a Popover element to ease developments that require
a popover. This component takes 2 props:
  - position='bottom' (optional): 'top', 'bottom', 'left', 'right'
  - title (optional)

Its usage requires setting an `opened` slot for the content of the
popover, whilst the 'trigger' of the popover uses the default slot.

E.g.
```xml
<Parent>
 <Popover>
  <t t-set="opened">
   <p>You have opened the popover, congratulations!</p>
   <button t-on-click='_handlerOnParent'>Dispatch cake</button>
  </t>
  <button class="btn btn-primary">Click me!</button>
 </Popover>
</Parent>
```

Note that:
- only one popover can be opened at a time (opening a popover will
close any previously opened popover)
- `Popover` uses `Portal` under the hood, so events are propagated
correctly even though the popover is teleported elsewhere in the dom
(see example in this commit message with `_handlerOnParent`)
- `<Popover>` is registed as a global component in QWeb and does not
need to be added to a Component's subcomponents list
