winaccessibility: let CoCreateInstance calls find the components
The COM services are not found because they are not registered in the
registry via regsvr32 (doing that is unnecessary since the components
are only instantiated by winaccessibility code and undesirable since
that would likely register the IAccessible2 types too, breaking A11y
tools) and the special manifest resource #97 that ActivateActContext()
tries to load does not exist in UAccCOM.dll; this would need to be a
XML manifest, the *.rgs and *.tlb that are already included as
individual resources won't work.
After reading ATL headers for hours it is immediately obvious that the
COM components can simply be registered by a call to
CComModule::RegisterClassObjects() from DllMain; this just requires
actually loading the UAccCOM library from somewhere so the DllMain runs.
