[HOTFIX] Fix After alter table add column schemaOrdinal is not continuous

Why is this PR needed?

Consider a scenario with complex columns[c1 int, c2 array, c3 array] here schema ordinal of child columns are -1. so c1, c2, c3 has ordinal 0, 1, 2. After alter table add column "c4 int", its ordinal should be 3. But currently it is 6 (due to flat column schema).
This will give problem when this ordinal is referred for some other functionality like rearrange projection columns.

What changes were proposed in this PR?

make schema ordinal continuous by collecting previous schema ordinal max.

Does this PR introduce any user interface change?

No

Is any new testcase added?

No

This closes #3577
