CMIS: Implemented the CheckOut button of the InfoBar

Implementing it needed:
+ Adding XCmisDocument::checkOut method and implement it in SfxBaseModel
+ Moving the CMIS properties loading into a SfxBaseModel private method to
factorize code.
+ Adding the SfxInfoBarContainerChild registration in all modules
