- Hide the change layout button
- Force one column view layout

Task Id: 1904747

This rev. adapts the code of the 'Add to Dashboard' entry of the
Favotires menu, according to the large SearchView refactoring. It
also does some tweaks for the dashboard app due to the move of the
ControlPanel from the ActionManager to the controllers.

- The dropdown structure was simplified, allowing to get rid of the
  3-levels structure induced by <ul/> elements and dropdowns can now
  contain anything. The class 'dropdown-item' is now mandatory for
  each dropdown clickable element. The class 'dropdown-item-text' can
  be used to add same padding and style but without making the element
  have a clickable look.

- Dividers now use the class 'dropdown-divider'

- The way dropdowns are opened and hidden also changed (before the
  'open' class was added on the `.dropdown-menu` parent, now the
  'show' class is added on both the `.dropdown-menu` parent and the
  `.dropdown-menu` itself).

- JS-wise, no click event handlers can be put on `.dropdown-toggle`
  elements anymore (instead, use handlers for dropdown events).

- Carets are automatically put on `.dropdown-toggle` elements, so this
  commit replaces the `.caret` elements with this. This feature was
  possible to disable but would prevent us from adding a caret with
  scss. Also, this simplifies the DOM. The 'o-no-caret' class was also
  introduced to allow using the 'dropdown-toggle' class on non-caret
  elements.

- Also adapt the scss to use $caret-width instead of $caret-width-base

Odoo made the bad choice of using the 'btn-sm' class for every button
instead of configuring the padding for default 'btn' to be smaller.
In BS4, the style of btn-sm is actually more complex, lowering the
font-size too. Also, btn-xs was removed so we would not have the
possibility to display smaller button than our default ones.

This commit removes btn-sm wherever it was used. Unfortunately, this
might remove it at some places where it made sense but this can be
restored in a second time.

Today, Odoo is really tricky to use without seeing the screen, it must be improved to be usable.

This PR forbid to use labels without a "for" attribute, add some title, rule and aria attributes in HTML. With that, Odoo will be fully usable with a screen reader.

Small fixes on nocontent onboarding screens.

Initial commit: https://github.com/odoo/odoo/commit/a87d761fdbf345ada5dc93e0a686b08a0f5a0417

Details:

- list: centered;
- pivot/graph: centered + empty folder face;
- Dashboard app with nocontent helper;
- Discuss inbox/starred: centered without neutral/smiling faces;
    => no faces because it's too much with animated
       rainbow man when emptying the any of the boxes.
- hr_holidays: fixed onboarding screens;
- (technical) dropped obsolete 'o_view_nocontent_container' style;
- manual reconciliation 'nothing to reconcile': centered + inside form sheet;
    => renamed account's o_view_nocontent to o_view_noreconciliation,
       so that it doesn't use the style of views.less.
- kanban: nocontent helper above the columns (if any);
- texts "no order to upsell"/"abandonned cart" paragraph split in two.

Before this rev., the dashboard wasn't rendered correctly when
the same action (same action id) was several times in the
dashboard.

For instance, if the dashboard contained the list and kanban view
of an action, both views were rendered in the same block, leaving
the other one empty. Moreover, (un)foldeing one automatically
(un)folded the other one.

This was because the action id was used to identify each view, but
this id is not unique in the dashboard. We now use a generated id
instead, which is unique.
