HDFFV-8146 - Remove "multi-chunk IO without optimization" sub-feature from MPI I/O optimization for chunked dataset feature
Description:
The “multi-chunk IO without optimization” feature is removed and made the related xfer property (H5FD_MPIO_CHUNK_MULTI_IO) go directly to “multi-chunk-io” feature.
Also update/fix/cleanup testings (chunk collective IO and actual chunk opt mode) accordingly.
Tested:
jam (linux32-LE), koala (linux64-LE), ostrich (linuxppc64-BE), fred (mac64-LE), Windows (32-LE cmake), cmake (jam)
