erofs-utils: mkfs: support compact indexes for bigpcluster

This adds support to generate big pcluster compact indexes.

Different from non big pcluster, blkaddr recorded in each pack is
the 1st pcluster blkaddr with a valid CBLKCNT since we don't know
compressed block count of each pcluster when reading HEAD lcluster.

For more details, also see related kernel commits.
