[ion] 25384: - Implement ObFindHandleForObject and add it to the NDK. However, it depends on ExEnumHandleTable which is still unimplemented. - Fix up prototype of the function (it returns TRUE/FALSE, not NTSTATUS) and fix callers to use it properly. - Also add ExEnumHandleTable to NDK.

Log:
- Implement ObFindHandleForObject and add it to the NDK. However, it depends on
ExEnumHandleTable which is still unimplemented.
- Fix up prototype of the function (it returns TRUE/FALSE, not NTSTATUS) and fix callers
to use it properly.
- Also add ExEnumHandleTable to NDK.
