PHP 8.4 | Test Helpers: fix trigger_error() with E_USER_ERROR is deprecated (Trac 62061)

[jrfnl]

PHP 8.4 | WP_Test_Stream::open(): fix trigger_error() with E_USER_ERROR is deprecated

PHP 8.4 deprecates the use of trigger_errror() with E_USER_ERROR as the error level, as there are a number of gotchas to this way of creating a Fatal Error (finally blocks not executing, destructors not executing). The recommended replacements are either to use exceptions or to do a hard exit.

As this is a test-only class, we don't have to take BC-breaks into account.

Also, as this is a test helper, throwing a exception is the most appropriate solution.
