Same change in several areas where translations existed:
- website editor notification popup
- elearning share popup
- forum remediation filter popup
- event registration attendees popup
- portal rating popup
- stripe payment error popup
And many other locations where there were no translations yet
"×" has been replaced by its UTF8 character.
Also introduced aria-label where missing.

Before this commit the close icon was included in translated resources.
For example, in Spanish the "×" had been turned into "&veces;"
thus not rendering an icon anymore

After this commit the close icon is not a translated text anymore and
remains an icon across all languages

Prior to this commit the close button of the notification is wrongly
placed when no title is provided.

Applying this commit places the close button at the right end. This commit also
modifies the size of the buttons to btn-sm.

Currently, it is not possible to have one line notification,
when you are not passing the title parameter as an option when
generating the notification,then it will display the blank div
with the default button icon only. so it is not possible to have
one-line notifications since the title is mandatory.

So the purpose of the task is to make the title optional, allowing
for more minimalistic notification.

Also removed some unnecessary titles from the notification and
some stying change.

This commit also increase the autoclose delay of non sticky
notifications, from 2.5s to 4s.

Make the notification system better, using bootstrap toast component,
and make it available in the frontend.

The toast component allowed to remove some JS code and made the
component customizable by themes but it had to be reviewed/fixed to make
it functional (maybe bootstrap will review its work in next versions).

This work should still be improved because there are still too many
ways (deprecated and not deprecated) to instantiate toasts in the
backend. The goal here was however to make the toasts more modern and
make them available in the frontend.

This work is needed for some tasks. @kig-odoo and @fja-odoo made a
pre-work to instantiate toasts in the frontend for their respective
tasks. This commit unifies the system.
