Introduce PermissionManager service

Introduce PermissionManager service

First iteration of adding a PermissionManager service as a replacement
for Title::userCan and User::isBlockedFrom methods.

- Created PermissionManager service
- Migrated Title::userCan to PermissionManager::userCan and deprecated the first
- Migrated Title::quickUserCan to PermissionManager::quickUserCan and deprecated the first
- Migrated User::isBlockedFrom to PermissionManager::isBlockedFrom and deprecated the first

Same for User::isBlockedFrom and PermissionManager::isBlockedFrom - the
$user parameter is now required so the declaration is changed from
isBlockedFrom( $title, ... ) to isBlockedFrom( $user, $title, .. ) which
means before User::isBlockedFrom removal all calls to it need to be updated.

Added PermissionManagerTest, it copies TitlePermissionTest but uses
PermissionManager instance instead of Title methods, this way keeping both tests
in place, we can ensure that nothing was broken and both are in working state
during the deprecation phase.
