Subject: Add QPA session manager

The QSessionManager doesn't allow customization in platform independent
way. The new QPlatformSessionManager aims to change that. Now the
QSessionManagerPrivate has a new QPlatformSessionManager member to
forward all the calls to QSessionManager's functions. If no platform
manager is present, the current behavior is used.
QPlatformSessionManager mimics the current QSessionManager behavior.

A new factory function has been added to QPlatformIntegration to return
a QPlatformSessionManager

Task-number: QTBUG-28228
