[php-src] Issue #20968: mysqli::options does not respect error reporting configuration

Issue: https://github.com/php/php-src/issues/20968
Author: morozov

### Description

The following code:

```php
<?php

$mysqli = new mysqli();
$value = $mysqli->options(-1, 'invalid_option');
var_dump($value);
```

Resulted in this output:
```
bool(false)
```

But I expected this output instead:
```
mysqli_sql_exception
```

Per the [`mysqli::options` documentation](https://www.php.net/manual/en/mysqli.options.php),

> If mysqli error reporting is enabled (**[`MYSQLI_REPORT_ERROR`](https://www.php.net/manual/en/mysqli.constants.php#constant.mysqli-report-error)**) and the requested operation fails, a warning is generated. If, in addition, the mode is set to **[`MYSQLI_REPORT_STRICT`](https://www.php.net/manual/en/mysqli.constants.php#constant.mysqli-report-strict)**, a [mysqli_sql_exception](https://www.php.net/manual/en/class.mysqli-sql-exception.php) is thrown instead.

Per the [`mysqli_driver::$report_mode` documentation](https://www.php.net/manual/en/mysqli-driver.report-mode.php), this should be the default behavior:

> PHP 8.1. The default value is now `MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT`. Previously, it was **[`MYSQLI_REPORT_OFF`](https://www.php.net/manual/en/mysqli.constants.php#constant.mysqli-report-off)**.
 
For reference, `mysqli::set_charset` behaves as expected:
```php
<?php

$mysqli = new mysqli('127.0.0.1', 'root', 'Passw0rd!');
try {
    $mysqli->set_charset('garbage');
} catch (mysqli_sql_exception $e) {
    echo 'Caught exception: ',  $e->getMessage(), "\n";
}
// Caught exception: Invalid character set was provided
```
