This commit removes all the 'extend' initially introduced to avoid code
repetition and ensure visual consistency across Bootstrap and Owl dropdowns.
Despite achieving the desired results, using 'extend' in this context
was seriously impacting the bundle generation time, probably due to an
underestimated amount of Apps' legacy-code applied on these elements.
In order to achieve the same results, the chosen strategy is to add
Bootstrap default classes directly into Owl dropdowns.
Also, it moves code related to bootstrap dropdown in 'webclient.scss',
leaving 'core/dropdown/dropdown.scss' for Owl code only.
Due to the discrepancies between Bootstrap and Owl html
structure, the '.dropdown-item' class could not have been added
directly to Owl's '.o_dropdown_item' itself, without refactoring
the Dropdown component structure.
// ==== Bootstrap 4.6 default Structure ================================
<div class="dropdown-menu">
<button class="dropdown-item" type="button">Action</button>
<a class="dropdown-item" href="#">Another action</a>
</div>
// ==== OWL default Structure before this commit =======================
<ul class="o_dropdown_menu">
<li class="o_dropdown_item">
<span>Action</span>
</li>
<li class="o_dropdown_item">
<a href="#">Another action</a>
</li>
</ul>
// ==== OWL Structure after this commit ================================
<div class="o-dropdown--menu dropdown-menu">
<span class="dropdown-item">Action</span>
<a class="dropdown-item" href="#">Another action</a>
</div>
// ==== web.assets_backend.css Bundle Generation Comparison ============
