You can directly call store manager in your block file, Just keep below class in your construct,

public function __construct(
        \Magento\Catalog\Block\Product\Context $context,
        \Magento\Framework\Url\EncoderInterface $urlEncoder,
        \Magento\Framework\Json\EncoderInterface $jsonEncoder,
        \Magento\Framework\Stdlib\StringUtils $string,
        \Magento\Catalog\Helper\Product $productHelper,
        \Magento\Catalog\Model\ProductTypes\ConfigInterface $productTypeConfig,
        \Magento\Framework\Locale\FormatInterface $localeFormat,
        \Magento\Customer\Model\Session $customerSession,
        ProductRepositoryInterface $productRepository,
        \Magento\Framework\Pricing\PriceCurrencyInterface $priceCurrency,
        \Magento\Eav\Model\ResourceModel\Entity\Attribute\Group\CollectionFactory $groupCollectionFactory,
        array $data = []
    ) {
        parent::__construct(
            $context,
            $urlEncoder,
            $jsonEncoder,
            $string,
            $productHelper,
            $productTypeConfig,
            $localeFormat,
            $customerSession,
            $productRepository,
            $priceCurrency,
            $data
        );
        $this->groupCollectionFactory = $groupCollectionFactory;        
    }

If you needed storemanager you can directly call in your file as below way,

$this->_storeManager->getStore()->getId()

Remove generated folder from root and check.

You have to use the StockRegistryInterface, Also you have to see the extended class and pass all needed parameters to the parent constructor, in your class you extended this class

=>\Magento\Catalog\Block\Product\ListProduct

So you have to pass his parameters,

Try this code.

 <?php
namespace Tm\Stockinfo\Block\Product;

class Stockqty extends \Magento\Catalog\Block\Product\ListProduct
{

    protected $_stockRegistry;

    public function __construct(
        \Magento\Catalog\Block\Product\Context $context,
        \Magento\Framework\Data\Helper\PostHelper $postDataHelper,
        \Magento\Catalog\Model\Layer\Resolver $layerResolver,
        \Magento\Catalog\Api\CategoryRepositoryInterface $categoryRepository,
        \Magento\Framework\Url\Helper\Data $urlHelper,
        \Magento\CatalogInventory\Api\StockRegistryInterface $stockRegistry,
        array $data = [])
    {
            parent::__construct(
                $context,
                $postDataHelper,
                $layerResolver,
                $categoryRepository,
                $urlHelper,
                $data
                );
        $this->_stockRegistry = $stockRegistry;
    }

    public function getStockQty(
        $product)
    {
        $stockitem = $this->_stockRegistry->getStockItem($product->getId(),
            $product->getStore()
                ->getWebsiteId());
        $qtyStock = $stockitem->getData("qty");
        return $qtyStock;
    }
}

Please note that this code working on Magento 2.2.3, So you need to check the parent class in your version

Magento 2 – Fatal Error: Uncaught TypeError: Argument 1 Passed

You issue at $myclas = new MyClass();

To initialize this class you have to use the object manager or have to inject that class to your class.

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$myclass = $objectManager->create('{NameSpaceofClass}\MyClass');
