The $hasLangauges and $hasVariants checks were used in couple places,
which lead to the same code used in many places.
Following the DRY rule, let's implement a Service that can do that
check, and use that service everywhere in code.

MediaWiki Core defined $wgHideInterlanguageLinks that can be used to
disable the interwiki links. Minerva skin should respect this config,
furthermore, this config should take precedence over the Minerva's
$wgMinervaAlwaysShowLanguageButton config.

The isAllowedPageAction is used in multiple places (SkinMinerva
and in PageActions toolbar builder). This logic should be defined
in separate service, easy accessible for different parts of the
Minerva skin.
Changes:
- Introduced MinervaPagePermissions as a centralized place to manage
user permissions
- Introduced MinervaNoTitlePermissions, an NullObject pattern to
handle situations when we do not have Title object (like in CLI)
- removed Minerva.ContentHandler service as it's not required any
more
- moved all permission names into constants
- moved isTalkAllowed() into MinervaPermissions
- renamed isAllowedPageAction() it `isAllowed()` to not mix it
with PageActions. Those checks are used in many places, not only
on PageActions menu
- made isAllowed( watch ) more robust - now it checks that Title
is watchable
