Implement VMDebug API to mark a class "platform"
Add a native implementation of VMDebug.allowHiddenApiReflectionFrom
which takes a Class object and sets a new access flag
kAccSkipAccessChecks on the corresponding mirror::Class instance.
The function will throw a SecurityException if the process has not
been forked as Java debuggable.
hiddenapi::IsCallerInPlatformDex is extended to take an optional
argument of the mirror::Class of the caller. If it is set and
the class has kAccSkipAccessChecks, the caller is allowed to
acccess non-SDK APIs.
Note that the mirror::Class of the caller is only provided for
reflection and JNI. The access flag is ignored for other means of
access.
