What problem does this PR solve?

if the task is full+incremental, we can use table structures from dump file to initiate schema tracker. Compared with using downstream table structure, that's better for the scenario when downstream has more columns.

this is done previously but canceled in pingcap/dm#1915 , because at that time with this feature, generating WHERE clause uses upstream PK/UK which will cause data lost. Now we have merged #3168 so this feature can be turned on without correctness problem.

What is changed and how it works?

revert pingcap/dm#1915

I forget that whether we have an integration test like create table(id int auto increment, uk int unique) and remove auto increment in downstream. If no, add it in this pr or later downstream PK/UK pr is OK

not understand 🤔 do you mean we should check that we're using downstream PK/UK to generate DML? #3168 should cover the test.

and there's a test to ensure original AskTUG issue is fixed.

Just a suggestion about using a common case to test for both features. Can ignore.
