SkinMustache in core provides most of what is required for Vector to
generate its menus. In the interest of having a canonical source of
truth for menus across all skins, Vector should use this data.
To ensure the HTML generated is (mostly) the same after this patch to
prior, a few modifications are necessary:
* The data from core is decorated so that Vector can continue having its
own custom class names on menus. This is done using the
decoratePortletClass method.
* There is no support for a menu having a header representing the
selected menu item, as is currently the case with variants. This is
achieved via an extension to getPortletData. It's assumed that later
when variants are merged with languages, this can be removed.
* Menus are agnostic to how they are displayed, so we must continue to
add the is-dropdown template variable to drop down menus. In future we
may want to rethink our Menu partial to make this unnecessary in PHP.
* The portal-first class is redundant in the modern Vector as we can
use the first-child selector. Previously we introduced a class to
service the legacy skin where this rule doesn't apply as #p-logo is
the first child. However, the legacy skin can do this using a special
next sibling selector instead.

Drop support for vectorMenu, vectorTabs and
vectorMenuCheckbox, body, menu selectors in preference
for standard selectors.
This change will impact a large amount of user scripts/styles but should
not impact any gadgets.
These classes were kept around for user scripts and styles however are not
needed internally. As we transition to a more maintainable skin menu
system, it is time to lose these selectors even though this will cause
disruption.
Vector now will use the mw-portlet class rather than the vector-menu
class in its own CSS styling, however it keeps the other classes to
allow differentiation of the different types of menu.
Changes to test: Previously the tests assumed all portlets were empty
when checking the classes. This is very rare, so its better to check
the classes of non-empty portlets, so several tests are updated
accordingly to drop the emptyPortlet class.

Split out the sidebar in advance of significant Latest mode only
changes.
The Less split was made by adding a new Sidebar.less file that imports
the Legacy implementation.
The Mustache split was made by file copying the existing implementation
into a legacy/ subfolder. Both the Legacy and Latest implementations
were then stripped of templates not applicable to their modes.
These changes are aligned with the splits for JavaScript.
