Manually convert deprecation_test.module functions to OOP

There is no mr, testing the status.

I moved functions

• deprecation_test_deprecated_hook
• deprecation_test_deprecated_alter_alter

to Drupal\deprecation_test\Hook\DeprecationTestHooks class
And it become very similar to Drupal\deprecation_hook_attribute_test\Hook\DeprecationHookAttributeTestHooks.

Should we remove module deprecation_hook_attribute_test at all?
Or is it better to remove class Drupal\deprecation_test\Hook\DeprecationTestHooks?

I apologize, this was in the wrong group.

This explicitly tests procedural deprecated hooks and deprecated hook_alters.

We cannot convert this yet.

It might be worth adding more comments to call this out in the module.
