Revert "SWDEV-433371 - use comgr to unbundle code objects"

This reverts commit c0ee0ffa1c.

Reason for revert: <INSERT REASONING HERE>
New comgr unbundling action leads to perf drop for uncompressed code object.   Will create a new patch to use old path for uncompressed , new unbundling api for compressed .
