[jdk17u] RFR: 8277195 missing CAccessibility definition in [CommonComponentAccessib…

[Artem Semenov]

A part of the fix JDK-8274381 has already been back ported to 17u, however after the fix JDK-8267385 the rest changes need to be back ported too. 

It's this chunk: 

- (id)accessibilityHitTest:(NSPoint)point 
{ 
    JNIEnv* env = [ThreadUtilities getJNIEnv]; 

+ GET_CACCESSIBILITY_CLASS_RETURN(nil);
