The SortedDataInterface requires that setEndPosition should be called before seeking because the cursor bound is only set in seek. If an endPosition is set after seek, it has no effect and the cursor can be advanced beyond the end bound. Therefore we should throw an error in advanceNext and force the caller to re-seek.

We should also allow setEndPosition on an unpositioned cursor without first calling seek. The idea is that the cursor should start from the start and stop at the end bound.

Adopt _needSeek code and tests from SERVER-90281.
