Migrate all callers of Hooks::run() to use the new
HookContainer/HookRunner system.
General principles:
* Use DI if it is already used. We're not changing the way state is
managed in this patch.
* HookContainer is always injected, not HookRunner. HookContainer
is a service, it's a more generic interface, it is the only
thing that provides isRegistered() which is needed in some cases,
and a HookRunner can be efficiently constructed from it
(confirmed by benchmark). Because HookContainer is needed
for object construction, it is also needed by all factories.
* "Ask your friendly local base class". Big hierarchies like
SpecialPage and ApiBase have getHookContainer() and getHookRunner()
methods in the base class, and classes that extend that base class
are not expected to know or care where the base class gets its
HookContainer from.
* ProtectedHookAccessorTrait provides protected getHookContainer() and
getHookRunner() methods, getting them from the global service
container. The point of this is to ease migration to DI by ensuring
that call sites ask their local friendly base class rather than
getting a HookRunner from the service container directly.
* Private $this->hookRunner. In some smaller classes where accessor
methods did not seem warranted, there is a private HookRunner property
which is accessed directly. Very rarely (two cases), there is a
protected property, for consistency with code that conventionally
assumes protected=private, but in cases where the class might actually
be overridden, a protected accessor is preferred over a protected
property.
* The last resort: Hooks::runner(). Mostly for static, file-scope and
global code. In a few cases it was used for objects with broken
construction schemes, out of horror or laziness.

Since the hook interfaces are not yet released and adding a parameter
to the hook is b/c, I have just added a parameter without introducing
a new version of the hook interface

This converts user options management to a separate
service for use in DI context.
User options are accessed quite early on in installation
process and full-on options management depends on the
database. Prior we have protected from accessing the DB
by setting a hacky $wgUser with 0 id, and relying on the
implementation that it doesn't go into the database to
get the default user options. Now we can't really do that
since DBLoadBalancer is required to instantiate the options
manager. Instead, we redefine the options manager with
a DefaultOptionsManager, that only provides access to
default options and doesn't require DB access.
UserOptionsManager uses PreferencesFactory, however
injecting it will produce a cyclic dependency. The problem
is that we separate options to different kinds, which are
inferred from the PreferencesFactory declaration for those
options (e.g. if it's a radio button in the UI declaration,
the option is of multiselect kind). This is plain wrong,
the dependency should be wise versa. This will be addressed
separately, since it's requires larger refactoring. For now
the PreferencesFactory is obtained on demand. This will be
addressed in a followup.
