[IMP] menu: more positioning options for Menu component

[hokolomopo]

The Menu component was taking a {x,y} props for its positioning.
This is not enough to cover that cases when we want the menu to be
positioned around a rectangle when there is not enough space for the
menu to be displayed at the bottom left.

With this commit:

• the menu of SelectMenu no longer overlap with the select
  when the menu is displayed upwards
• the menu of Figure is positioned to the right of the figure and only flip
  to the left if there is not enough space
• the menu of LinkEditor is positioned to the right of the menu button instead of a random position

Task: 4655815

review checklist

• feature is organized in plugin, or UI components
• support of duplicate sheet (deep copy)
• in model/core: ranges are Range object, and can be adapted (adaptRanges)
• in model/UI: ranges are strings (to show the user)
• undo-able commands (uses this.history.update)
• multiuser-able commands (has inverse commands and transformations where needed)
• new/updated/removed commands are documented
• exportable in excel
• translations (_t("qmsdf %s", abc))
• unit tested
• clean commented code
• track breaking changes
• doc is rebuild (npm run doc)
• status is correct in Odoo
