Break up Menu/DefaultBuilder into functions that are reusable without
inheritance. The functions do not need much state to produce their
outputs and a weighty inheritance hierarchy makes the code difficult to
reason about. The functions are used in a following patch for the user
menu. They're now simple, independent, static functions in BuilderUtil
that are easy to reason about and compose.
Also, ban inheritance via `final` in a few places nearby. Inheritance
has not worked well in MobileFrontend and enabling it should be a
special deliberate case, not a default. E.g., in the user menu, the
changes could have been to the base class' getPersonalTools() method
such that the client passes a parameter for the advanced config or maybe
just override it in the subclass. In either case, it makes the whole
hierarchy nuanced and harder to reason about for something that should
be dead simple.

We can define return types using `function(): TYPE` notation.
We should do that when it's possible.
For now, it's not possible to type nullable return type (PHP7.1
supports that, but PHP7.0 and most probably HVVM doesn't),

Changes:
- moved all menu elements definitions from SkinMinerva into
a separate Definitions.php file
- moved menu building from SkinMinerva into includes/menu/Main
folder
- introduced Builder pattern for easy menu building
Minerva/Menu/Main/Director takes an Minerva/Menu/Main/IBuilder
and builds the menu. The IBuilders use definitions from
Minerva/Menu/Definitions file, so all definitions can be shared
across different menus
- used ServiceWiring file to register MainMenu Director as Service
- left class_alias for old MenuBuilder as some extensions still use it
- The hooks system have to stay like that as some extensions
are using it (BlueSpiceMultiUpload and GrowthExperiments).
- introduced AdvancedMenu builder for the AMC mode
