PB 4f7a3fbbbd Restructure OLE-related doxygen documentation
All OLE-related classes and enums were described
in interface header msw/ole/automatn.h which led
to incorrectly listed include files in the generated
documentation for those classes and enum that
were actually declared in different include header files.

The documentation in the interface files has now been
split into files with names matching the actual include files.

Closes #18536

@class wxAutomationObject
The @b wxAutomationObject class represents an OLE automation object containing
a single data member,
an @c IDispatch pointer. It contains a number of functions that make it easy to
perform
automation operations, and set and get properties. The class makes heavy use of
the wxVariant class.
The usage of these classes is quite close to OLE automation usage in Visual
Basic. The API is
high-level, and the application can specify multiple properties in a single
string. The following example
gets the current Microsoft Excel instance, and if it exists, makes the active cell bold.
@code
wxAutomationObject excelObject;
if ( excelObject.GetInstance("Excel.Application") )
excelObject.PutProperty("ActiveCell.Font.Bold", true);
@endcode
Note that this class obviously works under Windows only.
