[php 8.4] [type-declaration] Add AddArrayAnyAllClosureParamTypeRector and NarrowArrayAnyAllNullableParamTypeRector

[TomasVotruba]

Two new PHP 8.4 type-declaration rules for array_any()/array_all() (and friends) closure params.

AddArrayAnyAllClosureParamTypeRector

Adds a type to an untyped closure param, based on the array item type.

 /** @var string[] $items */
-array_any($items, fn ($item): bool => $item !== '');
+array_any($items, fn (string $item): bool => $item !== '');

Handles array_any(), array_all(). Only fills a param that has no type yet.

NarrowArrayAnyAllNullableParamTypeRector

Narrows an already nullable closure param to the non-nullable array item type.

 /** @var string[] $items */
-array_any($items, fn (?string $item): bool => $item !== '');
+array_any($items, fn (string $item): bool => $item !== '');

Handles array_any(), array_all(), array_find(), array_find_key(). Only acts on a ?type param, and skips when the item type is itself nullable.

The two rules are complementary and non-overlapping: one fills a missing type, the other tightens an existing nullable one.
