Written constructor for opffapi/com/sun/star/accessibility/AccessBridge.idl and rewritten to new style in offapi/com/sun/star/awt/tab/UnoControlTabPageModel.idl

Signed-off-by Stephan Bergmann <sbergman@redhat.com>:
* Moved offapi/com/sun/star/accessibility/AccessBridge.idl from _noheader to
  _nohdl, as necessary for a new-style service.
* Left out changes to offapi/com/sun/star/awt/tab/UnoControlTabPageModel.idl, as
  that appears to never be instantiated at the global component context/service
  manager, but rather via some local ControlModelContainerBase::createInstance
  in toolkit/source/controls/controlmodelcontainerbase.cxx, so does not look
  like it qualifies for a new-style service.
