Sergey Biryukov d7bb5d7227 Code Modernization: Explicitly declare all properties in WP_Test_Stream.
Dynamic (non-explicitly declared) properties are deprecated as of PHP 8.2 and are expected to become a fatal error in PHP 9.0.

The `WP_Test_Stream` class is a stream wrapper for use in the tests and must comply with the PHP requirements for such stream wrappers.

In this case, the class did not declare the required public `$context` property, which led to deprecation notices about the property being dynamically created from the `Tests_Image_Editor_Imagick::test_streams()` and `Tests_Image_Meta::test_stream()` tests.

Reference: [https://www.php.net/manual/en/class.streamwrapper.php#streamwrapper.props PHP Manual: streamWrapper: Properties].
