§H.12 step 14: C accessors for BMAPFMT block-ACL fields

Browse Source 
blk_owner_fp_get/_set, blk_acl_allow_get/_set, blk_acl_ttl_get/_set,
blk_flags_get/_set -- thin read-modify-write wrappers over the existing
blk_get_meta()/blk_set_meta() (caching/dirty-tracking already owned
there). Sets up the C-primitive layer FORTH wrappers (step 15) will call,
mirroring the word-level ACL system's own split.

Verified 3-arch boot to ok> (amd64/aarch64/riscv64).
