Remove chunk count check on the ChunkBuffer (#16868)
Summary:
Previously, the ChunkBuffer depends on the remaining chunk count to signal end of dataloading. This does not work with distributed samplers where each sampler only loads a subset of chunks. This refactor remove the dependency on the remaining chunk count at the ChunkBuffer.
