lok: set device form factor of the client on view creation

This patch allows the lok core to know about the device form facor of
the client requesting the creation of new view, immediately instead of
a later time.
When a new view is needed a "DeviceFormFactor" parameter is forwarded
to lo_documentLoadWithOptions and doc_createViewWithOptions from the
client.
This parameter can have one of the following values: 'desktop',
'tablet','mobile' and it is used to set a global variable accessible
by SfxLokHelper::setDeviceFormFactor and
SfxLokHelper::getDeviceFormFactor.
This global variable is retrived in the SfxViewShell constructor for
setting SfxViewShell::maLOKDeviceFormFactor attribute.
In SfxViewShell we have the following 3 methods:
- bool isLOKDesktop()
- bool isLOKTablet()
- bool isLOKMobilePhone()
which replace the following boolean functions:
- comphelper::LibreOfficeKit::isTablet
- comphelper::LibreOfficeKit::::isMobilePhone
