feat(frontend): add nexmark planner test

[skyzh]

Signed-off-by: Alex Chi [email protected]

What's changed and what's your intention?

• Only a few queries can be planned.
• Some of them failed because of parser error. Flink SQL's syntax is somehow different from Postgres.
• Window functions are expressed differently in RisingWave. Need rewrite some queries.

Checklist

• I have written necessary docs and comments
• I have added necessary unit tests and integration tests

I can't imagine you completed them so fast!
