planner/core: check the window func arg first before checking window specs (#11613)

[sre-bot]

cherry-pick #11613 to release-3.0

---

What problem does this PR solve?

Fix #11008.

What is changed and how it works?

it seems not a good idea but we need to be compatible with mysql.
so here, when extract windows funcs, it the continue to check the window arg. when checking window func arg, it need to be able to do the expression check.

Check List

Tests

• Unit test -- added
• Integration test -- the explain test tool is changed because the plan id increased. and the error EOF is ignored in test.

Code changes

• Has exported function/method change -- add a function to check the window args.

Side effects

• Increased code complexity and the process of parsing and check arg is done twice.

Hi, do you mean I need to fork from https://github.com/sre-bot/tidb/tree/release-3.0-4995fe741ea5 and create a PR into this branch?

I run the code and found it passed. is the code in CI not latest version? in previous commits, it will cause this problem.

building explain-test binary: ./explain_test
start tidb-server, log file: ./explain-test.out
tidb-server(PID: 27538) started
run all explain test cases

Great, All tests passed
explaintest end
➜  tidb git:(release-3.0-4995fe741ea5) 

after I merged from upstream/release-3.0 into release-3.0-4995fe741ea5, it's still passed.
