[CodeQuality] Add NegatedAndsToPositiveOrsRector

[TomasVotruba]

What

Adds a new rule NegatedAndsToPositiveOrsRector that applies De Morgan to a negated AND: !(A && B) → !A || !B.

This is the missing counterpart to the existing SimplifyDeMorganBinaryRector, which only handles a negated OR (!(A || B) → !A && !B). The two directions are kept as separate, focused rules.

Examples

Real-world case (empty() + in_array()):

-return !(!empty($limitToAssets) && !in_array($assetId, $limitToAssets));
+return empty($limitToAssets) || in_array($assetId, $limitToAssets);

Comparison operators:

 $a = 5;
 $b = 10;
-$result = !($a > 20 && $b <= 50);
+$result = $a <= 20 || $b > 50;

What changed

• New rule rules/CodeQuality/Rector/BooleanNot/NegatedAndsToPositiveOrsRector.php — subscribes to BooleanNot, transforms a wrapped BooleanAnd into a BooleanOr of the inverted operands.
• BinaryOpManipulator::inverseBooleanAnd() — new helper mirroring inverseBooleanOr(); inverts each operand and joins with ||. Skips nested && to avoid partial rewrites. The shared resolveInversedNodeClass() is intentionally untouched, since invertCondition() relies on it keeping operands in place.
• Registered in CodeQualityLevel::RULES.
• Tests under rules-tests/CodeQuality/Rector/BooleanNot/NegatedAndsToPositiveOrsRector/ — covers the empty/in_array case, comparison operators, and skip cases (negated OR, nested AND).

SimplifyDeMorganBinaryRector is left unchanged.
