Replace run!, test! and count! macros in test-suite to Tester methods,

[panarch]

Add run, count, test and named_test methods to Tester instance.
Apply pretty_assertions::assert_eq.

1. run

// before
run!("SELECT * From Foo;");

// after
g.run("SELECT * FROM Foo;").await.unwrap();

2. test

// as-is
test! {
    sql: "SELECT * FROM Foo",
    expected: Ok(select!( .. ))
};

// to-be
g.test(
    "SELECT * FROM Foo",
    Ok(select!( .. ));
).await

3. migrations
   migration work for existing test-suite modules are also simple.
   e.g. test-suite/src/case.rs

// as-is
for (sql, expected) in test_cases {
    test!(sql, expected);
}

// to-be
let g = get_tester!();

for (sql, expected) in test_cases {
    g.test(sql, expected).await;
}

remaining tasks

• metadata
• index
• function
• data_type
• arithmetic
• alter
• aggregate
• remove legacy macros - run!, test!, etc.
