Enable IAccessible2 for MinGW
MinGW 5.3 is able to compile the IAccessible2 classes. All that is needed
is some way to provide the missing IIDs, which is done via specialization
of a function template (similar to the MinGW's __uuidof operator).
[ChangeLog][Windows][Accessibility] MinGW builds now support IAccessible2.
