erofs: introduce physical cluster slab pools
Since multiple pcluster sizes could be used at once, the number of compressed pages will become a variable factor. It's necessary to introduce slab pools rather than a single slab cache now. This limits the pclustersize to 1M (Z_EROFS_PCLUSTER_MAX_SIZE), and get rid of the obsolete EROFS_FS_CLUSTER_PAGE_LIMIT, which has no use now.
