RFR: 8307145: windowsaccessbridge.dll is missing 4 critical methods in its C API [v2]

[Julian Waters]

> In windowsaccessbridge(-64).dll the following methods are exported in a def file to C API which in turn call their real implementation, which are instance methods of the class WinAccessBridge:
> 
> addJavaEventNotification
> removeJavaEventNotification
> addAccessibilityEventNotification
> removeAccessibilityEventNotification
> 
> 
> However, they are nowhere to be seen in the actual C interface, in AccessBridgeWindowsEntryPoints.cpp. Your guess is as good as mine as to how on earth MSVC is still capable of compiling and linking this without any errors whatsoever, but in any case, this is a severe oversight and should be properly defined in the C API lest this happy accident within MSVC is fixed by Microsoft in the future
