test(frontend): meaningful names for basic_query_{1,2,3}.yaml

[xiangjinwu]

What's changed and what's your intention?

• basic_query_1 -> basic_query: simple values, scan, filter, project, insert, delete
• basic_query_2 -> agg
• basic_query_3 -> expr: literal, cast, bool, cmp, atm, temporal, string, etc

Also moves test cases to designated files: +187 -187.
