Deprecate alpha, beta, gamma, delta and espilon color names and now use
a new color system: o-color-x, with x from 1 to 5.

This will allow to review the colors of all themes to have nice visuals
for the new color combinations classes, without breaking the current
uses of bg-alpha, alert-delta, etc in current websites of customers
(by keeping the old color and classes for compatibility).

This will also allow to uniformize all themes under the same conventions
to enforce BS color override:
- o-color-1 used as primary (as before, for alpha)
- o-color-2 used as secondary (as before, for beta)

Before, some themes were not following the 2 guidelines. The users
using those themes will simply have the possibility to choose o-color-1
and o-color-2 colors accordingly to restore their website without
breaking the new system features.

Another change is that those colors are defined through color palettes
and not theme color palettes. This will avoid them to generate automatic
bootstrap classes which we don't want (alert, btn) and generate the one
we want by ourself.

Note: for mass mailing, the colors and classes also have been renamed
but the system stays unchanged.

In 3f4092d837d50d25d6c9630d84f67545cf586c7a, the SummernoteManager that
was previously owned by RTE was removed, this was because the wysiwyg
already has one. One problem with this however is that when an editor is
created in an iframe, the wysiwyg is instanciated outside, while the
editor is instanciated inside. This means that they don't have the same
core.bus to listen for and trigger events, such as those used to open
the various editor dialogs. This commit fixes that by always using the
top-level core.bus when opening dialogs. This also has the advantage
that the dialogs are no longer confined to the iframe and can take up
the whole screen, making them more comfortable to use.

This commit, unfortunately, mixes three things:

- Restoring as much as possible the scss organisation to allow styling
the web_editor UI properly.

- Fixing some bugs like a border around the page once the editor is
loaded, no ability to scroll the snippets, etc

- Introducing a whole new UI for snippet options: a left panel instead
of the old dropdown & button overlay.

Note: this commit also do some linting and ES6 convertion even though
some of it has been done in the parent commit.

Note 2: some elements that were removed are still styled in the POS apps
but this is because part of a feature was removed while leaving dead
code behind, this is handled in another PR which is to be merged
(https://github.com/odoo/odoo/pull/36136).

The wysiwyg abstraction layer was introduced in saas-12.2 by
commit f2969923. Its goal was to provide an external interface
for other modules that wanted to use the editor feature such
that the editor core itself could be changed without requiring
extensive changes in the other modules.

This commit is adapting the wysiwyg interface to instantiate
the 12.0 editor below it rather than the saas-12.2 one, thus
reverting the "new editor" part of f2969923 itself.

Part of PR 35677.

Following the refactoring of the web_editor (JS & CSS) when adding a
long link in a task's description the line starts to overflow from the
field and create an horizontal scroll.

This commit restores the CSS word-wrap properties to the form field html
allowing to nicely break the line on a word basis, preventing a possible
overflow.

Also it doesn't make sense to apply it on an iframe.

* Creating a new structure by transforming all the plugins in the
  library using the odoo inheritance system. Plugins are easier to
  implement with the AbstractPlugin to add Odoo behaviors.

* From now on, the methods of the library (in this case Summernote) can
  no longer be called by other modules or files. Only the wysiwyg
  widgets can access it, to simplify the updating process. The wysiwyg
  object serves as an interface.

* Depending on the options the snippets will be loaded or not, the
  editor will be in an iframe or not... all of this is transparent from
  the outside.

* Regarding iframes, all controllers related to editing have been
  removed: the new API no longer needs them. This speeds up loading,
  eases testing and removes complexity for the same
  features.

PUBLIC FEATURES

There are several public methods on the Wysiwyg class:
* Wysiwyg.prepare (WidgetParent): returns a deferred resolved when the
  library (xml, lazy, assets...) is loaded.
* Wysiwyg.getRange (DOM): returns the range (selection in the dom)
* Wysiwyg.setRange (startNode, startOffset, endNode, endOffset): creates
  a range (selection in the dom)
* Wysiwyg.setRangeFromNode (DOM, options) that creates a range from an
  element (option available to select all, start or end)

A jQuery selector was added: :o_editable, which indicates whether the
current element is editable. That is, if it is contained in a tag with
the attribute 'contentEditable = "true"' or in a tag with the class
o_editable.
Several methods are also present:
* focusIn: makes a focus and places the cursor at the beginning of the
  element
* focusInEnd: makes a focus and places the cursor at the end of the
  element
* selectContent: makes a focus and selects the content

HTML FIELD

The HTML field can receive different options:
* style-inline: {boolean} transforms a class into an inline style when
  saving and vice versa when reading.
* no-attachment: {boolean} prevents the use of attachments (in media
  dialog)
* cssEdit: {xml_id} to use a template containing the css to loaded in
  an iframe when editing
* cssReadonly: {xml_id} to use a template containing the css to load
  into an iframe when viewing in readonly
* snippets: {xml_id} snippets template (can be used with or without
  cssEdit)
* wrapper: {template} qweb static template (containing a tag:
  id = "wrapper") that will include the content during editing (removed
  on save)

MASS MAILING

A widget was created for mass mailing. There are now two fields:
body_html and body_arch.
body_arch contains the code with the class without conversion into
inline style, useful when editing and one with the inline style that is
visible in readonly mode and sent by email.
Advantage: no spreading errors, able to update css/theme, able to do
more changes when converting to inline style so that a maximum of mail
clients have an impeccable rendering.

This is a simple renaming without adaptation.
