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

SkinOptions array was used to determine which options are available
for current session. Once we started extracting things from
SkinMinerva class, we found out that lots of things depend on
SkinOptions.
For example MainMenu/PageActionsMenu depend on skinsOptions var.
We could pass $skin object as dependency to a menu builder, but
this would cause a circural dependency (Skin depends on menu builder,
menu builder depends on skin) which is an anti-pattern.
In order to avoid such situations lets prepare first, and extract
the SkinOptions to a separate class, register it as a service
so different parts of Skin Minerva can freely use a single instance
of SkinOptions object.

SkinMinerva cached the ContentHandler object for better performance.
In the future the ContentHandler will be also used in the Menu,
for better readability, store ContentHandler as Service.
MediaWikiServices will initialize service on first access and cache
it for future needs. Same applies to SkinUserPageHelper,
