mem-cache: Add encoding bits to the data of multi compressors
When compressing using a multi-compressor, one must be able to
identify which sub-compressor should be used to decompress data.
This can be achieved by either adding encoding bits to block's
tag or data entry.
It was previously assumed that these encoding bits would be added
to the tag, but now make it a parameter that defaults to the data
entry.
