*: support auto_random table option (#16750)

[sre-bot]

cherry-pick #16750 to release-3.1

What problem does this PR solve?

Problem Summary: support auto_random_base table option

the conflict file is in:
1: `tables.go` function `RebaseAutoID`, interface Allocators is not cherry-picked. So change it to Allocator
2: `builder.go` lack of diff.type parameter.
3:  also fix a bug in `show.go` & `show_test.go`, the comment should be `/*T![auto_rand_base] xxx */`, I will do the same on the master soon

What is changed and how it works?

How it Works:
After this table option:
We can do the auto_random rebase by alter table xxx auto_random_base = num
Also we can specify the initial auto_random base by create table t xxx(xxx) auto_random_base = num
