### What problem does this PR solve?
Issue Number: close #65865
Related PR: #66664
Problem Summary: HLL, QUANTILE_STATE, and AGG_STATE columns in non-aggregate
table models can enter row conversion paths that do not support nullable
aggregate-state values and fail at runtime. Reject new definitions of these
types in Duplicate Key and Unique Key tables by default, while retaining a
temporary FE compatibility switch for migration. Existing Aggregate Key tables
remain supported.
### Release note
HLL, QUANTILE_STATE, and AGG_STATE columns are restricted to Aggregate Key
tables by default. The temporary FE config
`allow_non_aggregate_table_state_types=true` can restore the previous
definition behavior during migration and will be removed after the
compatibility transition period.
### Check List (For Author)
- Test: Unit Test / Build
- `./run-fe-ut.sh --run
org.apache.doris.nereids.trees.plans.commands.info.ColumnDefinitionTest`
- `./build.sh --fe`
- `./build.sh --be`
- Regression test added but not run because an isolated cluster rebuild
requires separate destructive-action approval
- Behavior changed: Yes. New HLL, QUANTILE_STATE, and AGG_STATE columns are
rejected in non-Aggregate Key tables by default
- Does this need documentation: No. The compatibility switch is temporary
and carries its removal notice in the FE config description
