[ANativeWindow] Add apex stub for getLastDequeueStartTime

Also adding private query64 hook so that timing queries can have
nanosecond precision. Otherwise with a 32-bit width we can only have
millisecond precision for timestamps and microsecond precision for time
intervals, and really we shouldn't need to be less precise if we can
help it.
