expression: forbid aggregate function with json type pushdown to tiflash wrongly

[wshwsh12]

What problem does this PR solve?

Issue Number: close #28753

Problem Summary:

What is changed and how it works?

Now tiflash support 8 aggregate function: Sum, Count, Min, Max, Avg, FirstRow, ApproxCountDistinct, GroupConcat
5 aggregate function is no need cast Agg funcs: Min, Max, FirstRow, Count, ApproxCountDistinct
3 aggregate function may exist implicit conversions: Sum, Avg(convert to Real), GroupConcat(convert to String)
All types except Duration and JSON are supported to convert to Real and String.
So we can prohibit the aggregate with json type pushing down.

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)
  Before this pr

use test;
drop table t;
create table t(a json);
insert into t values(null);
alter table t set tiflash replica 1;
select avg(a) from t;
ERROR 1105 (HY000): other error for mpp stream: Code: 0, e.displayText() = DB::TiFlashException: CastJsonAsReal is not supported., e.what() = DB::TiFlashException,
select sum(a) from t;
ERROR 1105 (HY000): other error for mpp stream: Code: 0, e.displayText() = DB::TiFlashException: CastJsonAsReal is not supported., e.what() = DB::TiFlashException,
select /*+ hash_agg() */  group_concat(a) from t;
ERROR 1105 (HY000): other error for mpp stream: Code: 0, e.displayText() = DB::TiFlashException: CastJsonAsString is not supported., e.what() = DB::TiFlashException,

After this pr
All the sum/avg/group_concat with json type can't push down to tiflash.
