[deprecation] Deprecate AddAssertArrayFromClassMethodDocblockRector

[TomasVotruba]

The rule reads a @param docblock type and injects a runtime Assert::all*() call at the top of the method.

 class SomeClass
 {
     /**
      * @param int[] $items
      */
     public function run(array $items)
     {
+        \Webmozart\Assert\Assert::allInteger($items);
     }
 }

Two problems:

• it pays a runtime cost on every call, including hot paths, to check something static analysis already checks for free
• it trusts the docblock. A stale or wrong @param turns into a hard runtime failure on input that was always valid.

That trade-off is a project-level decision, not a general upgrade. Write a custom rule where it is wanted.

Changes:

• rule implements DeprecatedInterface and throws on refactor()
• test cases + fixtures removed
• config/set/assert.php and SetList::ASSERT removed, the set held only this rule
• AssertClassName and ExistingAssertStaticCallResolver removed, they had no other user
