Migrate `Bl -column' phrases to be MDOC_BODY instead of MDOC_HEAD. This

will make it easy for re-entrant parsing of `Ta' macros to fit in with
standard closure rules.

Added some more regressions for `Bl -column'.  Note that one should
fail, as documented in the TODO file.

Recorded change of AST BNF in mdoc.3.
