Add currentStmt property on AbstractRector to allow pull Scope from it on deep Expr

[samsonasik]

Currently, on out of control deep Expr, like this:

$$param = $$bar = $zzz = self::decodeValue($result->getItem()->getTextContent());

we currrently direct pull Scope from File:

        // too deep Expr, eg: $$param = $$bar = self::decodeValue($result->getItem()->getTextContent());
        if ($node instanceof Expr && $node->getAttribute(AttributeKey::EXPRESSION_DEPTH) >= 2) {
            return $this->scopeFactory->createFromFile($filePath);
        }

Instead, I think we can pull Scope from nearest current Stmt, which can be pulled on AbstractRector when verify current valid Node, check nearest Stmt before match:

    private function isMatchingNodeType(Node $node): bool
    {
        $nodeClass = $node::class;
        foreach ($this->getNodeTypes() as $nodeType) {
            if (! is_a($nodeClass, $nodeType, true)) {
+                if ($node instanceof Stmt) {
+                    $this->currentStmt = $node;
+                }

                continue;
            }

            return true;
        }

        return false;
    }

so we can pull Scope from there.

All checks have passed 🎉 @TomasVotruba it is ready for review.

Rebased 👍

I think if it need to be applied, it should be a "nodeHolder" property, as when passed is a ClassMethod, the holder is for example: a Class_, when Assign, the holder can be an Expression stmt.

That's we may can know if the holder is no longer belong to the node on RectifiedAnalyzer on multi rules apply so can be skippable instead of continue.

Let's ship it 👍
