Implement tooltip API for the following actions

What does this MR do?

This Merge Request continues the work started in:

• !36452 (merged)
• !39379 (merged)

This MR has the goal of exposing an API to perform the following actions in tooltips:

• Enable/disable a tooltip.
• Hide/show a tooltip.
• Update a tooltip’s content based on the target’s title.

How to test?

Replace the following snippet in app/assets/javascripts/main.js:

  // Initialize tooltips
  $body.tooltip({
    selector: '.has-tooltip, [data-toggle="tooltip"]',
    trigger: 'hover',
    boundary: 'viewport',
    delay,
  });

with

  initTooltips('.has-tooltip, [data-toggle="tooltip"]:not([data-original-title])', {
    triggers: 'hover',
    boundary: 'viewport',
  });

Afterwards, you can find any place in the application where Bootstrap’s tooltip API is called and replace that API call with the API created on this MR. For example, you can replace the following API call in https://gitlab.com/gitlab-org/gitlab/-/blob/master/app/assets/javascripts/project_label_subscription.js#L69:

import { fixTitle } from '~/tooltips';

// replace this
$button.attr('title', newTitle).tooltip('_fixTitle');

// with this
fixTitle($button);

Or you can just apply this patch test_tooltip.patch
