获取特定层级视图项的合并样本。合并样本通过 outValues 参数，作为浮点值列表返回。
When HierarchyFrameDataView.ViewMode.MergeSamplesWithTheSameName is active, samples with the same name, and at the same hierarchy level, are merged and represented by a single item. In this case, HierarchyFrameDataView.GetItemColumnData represents an aggregated value.
Use GetItemMergedSamplesColumnDataAsFloats to obtain float values for individual samples in a merged hierarchy.
The resulting list of floats is written to outValues. This list is resized if necessary.
