Support mysql client prepare field type identification

[Yurunsoft]

This problem may also affect the operation of JSON fields, resulting in values in JSON being strings

<?php

use Swoole\Coroutine\MySQL;
use function Swoole\Coroutine\run;

run(function () {
    $db = new MySQL();
    var_dump($db->connect([
        'host'     => '127.0.0.1',
        'port'     => 3306,
        'user'     => 'root',
        'password' => 'root',
        'database' => 'db_imi_test',
    ]));
    $stmt = $db->prepare('select ? as a, ? as b, ? as c, ? as d, ? + ? as e');
    if (false == $stmt)
    {
        var_dump($db->errno, $db->error);

        return;
    }
    else
    {
        $ret2 = $stmt->execute([123, 3.14, true, false, 11, 22]);
        var_dump($ret2);
    }
});

wrong:

bool(true)
array(1) {
  [0]=>
  array(5) {
    ["a"]=>
    string(3) "123"
    ["b"]=>
    string(4) "3.14"
    ["c"]=>
    string(1) "1"
    ["d"]=>
    string(0) ""
    ["e"]=>
    float(33)
  }
}

right:

bool(true)
array(1) {
  [0]=>
  array(5) {
    ["a"]=>
    int(123)
    ["b"]=>
    float(3.14)
    ["c"]=>
    int(1)
    ["d"]=>
    int(0)
    ["e"]=>
    int(33)
  }
}
