[TypeDeclarationDocblocks] Deprecate 3 data provider docblock rules

[TomasVotruba]

Data provider docblock typing is not relevant to code quality. It increases maintenance cost and decreases readability of the test class.

Deprecated rules:

• AddReturnArrayDocblockFromDataProviderParamRector
• AddReturnDocblockDataProviderRector
• AddParamArrayDocblockFromDataProviderRector

All three now implement DeprecatedInterface, so registering them prints a deprecation warning; refactor() throws. Tests and fixtures are removed.

The last two were part of TypeDeclarationDocblocksLevel and are dropped from it. The first was in no set.

What the rules used to do:

 final class SomeTest extends TestCase
 {
+    /**
+     * @param string[] $names
+     */
     #[DataProvider('provideNames')]
     public function test(array $names)
     {
     }

+    /**
+     * @return array<array<string>>
+     */
     public static function provideNames(): array
     {
         return [[['John', 'Jane']]];
     }
 }

Native type rules on data providers stay untouched: ReturnIteratorInDataProviderRector and AddParamTypeBasedOnPHPUnitDataProviderRector.
