MDEV-36132 [wip] vcol expr to vcol field substitution in GROUP BY
Also update join->all_fields whenever substitution happens, and append
ref_pointer_array when needed.

If at least one item in ORDER BY or GROUP BY has been substituted by a
vcol this way, recount field types and recompute table index covering.

Added tests for GROUP BY subst and table index covering.

WIP TODOs:
- code documentation incl. the function subst_vcols_in_order
- do we need to deduplicate - see the TODO in subst_vcols_in_order
