Aleksey Midenkov 1037f95941 MDEV-33675 Assertion(reclength < vreclength) in setup_vcols_for_repair() 
When table2myisam() prepares recinfo structures BIT field was skipped
because pack_length_in_rec() returns 0. Instead of BIT field
DB_ROW_HASH_1 field was taken into recinfo structure and its length
was added to reclength. This is wrong because not stored fields must
not be prepared as record columns (MI_COLUMNDEF) in storage
layer. 0-length fields are prepared in "reserve space for null bits"
branch.

The problem only occurs with tables where there is no data for the
main record outside of the null bits.

The fix updates minpos condition so we avoid fields after
stored_rec_length and these are not stored by
definition. share->reclength already includes not stored lengths from
CREATE TABLE so we cannot use it as minpos starting point.

In Aria there is no "reserve space for null bits" and it does not
create column definition for BIT. Also there is no
setup_vcols_for_repair() to reproduce the issue. But nonetheless it
creates column definition for not stored fields redundantly, so we
patch table2maria() as well. The test case for Aria tries to
demonstrate BIT field works, it does not reproduce any issues (as
redundant column definition for not stored field seem to not cause any
problems).
