Test framework: Introduce the annotation @expectedDeprecated, modeled after PHPUnit's @expectedException.

Browse Source 
It works for both functions and arguments (using the value of the first argument passed to _deprecated_function() or _deprecated_argument(), which is typically the function name). It asserts both ways:
 * If specified, those deprecated notices must be caught, or the test fails.
 * If not specified, any other deprecated notices cause the test to fail.

Works regardless of WP_DEBUG.
see #25282.
