Before this commit the dimensions of the tour tip text obtained from
the text content was forced onto the complete active tooltip, sometimes
hiding a part of the text because the complete tooltip had additional
borders that prevent the text from using the same space as during the
measurement.

After this commit the dimensions of the tour tip text is computed by
taking the measure on the full tip by temporarily switching it to the
text display during initialization.

This commit improves the "Start tour" dialog accessible via the
DebugManager. It is now possible to reset a tour to its initial
step, so that it can be re-executed (in onboarding mode). The
content of the dialog has been reworked as well:
  - testing tours are displayed in another table
  - tour sequence is displayed
  - tours are sorted by sequence, and by name.

Now that the debug mode is stored in session, we need a clear indication that
debug mode is activated.
In backend, the 'fa-bug' is doing the trick but in frontend there is no visible
clue that debug mode is enabled.

This commit separate the debug manager code/feature so we can instanciate it in
frontend only with usefull options (such as enable assets, leave debug mode..).

Now, in frontend, people having access to the navbar (o_main_navbar) will see
the same 'fa-bug' icon with minimal options as mentioned above.
Also, in the footer, there will be another 'fa-bug' icon without any options.
It will be usefull when the navbar is not shown, typically the case for
public user, or for portal (without website installed)).
Clicking on it will simply leave debug mode as hinted in tooltip.

Closes #33213

`table-condensed` -> `table-sm`

Also SCSS variables were renamed.
Also restore list view design.

- 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.

Closes #14336

* The debug manager contains a feature to launch tours, adapt it
to new web_tour.tour system
* The website help menu allowed to relaunch tutorial tour in debug
mode. This feature is not adapted to new tour system and was useless
in the first place (debug mode in frontend is barely used anyway).
-> remove the website help menu and the feature
