enable_fast_schema_evolution 参数可以动态配置，兼容历史表 #43076

Feature request

Is your feature request related to a problem? Please describe.

当前 enable_fast_schema_evolution 参数不支持动态配置，只有建表的时候才可以设置，这样的话，导致历史表无法修改，无法实现 fast schema change， 对于一直使用的老用户来说，集群都是升级上来的，存在大量历史表，如果想使用 fast schema change 的话，就需要全部重新创建并导入历史数据，这种操作太费时费力

Describe the solution you'd like

希望可以通过动态配置参数的方式，历史表也可以实现 fast schema change。
