ModuleHandler->alterDeprecated does not properly handle deprecated OOP hooks

Problem/Motivation

When a deprecated hook is altered using a hook attribute instead of a procedural hook the method is not stored for the deprecation.

Steps to reproduce

Convert the test module deprecation_test to OOP hooks and core/tests/Drupal/KernelTests/Core/Extension/ModuleHandlerDeprecatedHookTest.php will fail.

Proposed resolution

Handle both alter deprecations for both OOP and procedural hooks.
Update the message to refer to only the location so it works for both procedural and OOP.

Remaining tasks

Also should we add a message if the alter test is failing that the deprecation procedural hook should not be converted until it's the last one?
Is the module implementing the hook enough for the deprecation message?
