Improve HreflangLoader performance	NEXT-173312

Core

• Changed \Shopware\Core\Content\Seo\HreflangLoader to use plain SQL and make use of an existing index on the seo_url table, thus greatly improving the performance.
• Deprecated protected method \Shopware\Core\Content\Seo\HreflangLoader::generateHreflangHome(), that method will be removed in v6.5.0.0, use \Shopware\Core\Content\Seo\HreflangLoader::load() with route = 'frontend.home.page' instead.

Refactoring of HreflangLoader

The protected method \Shopware\Core\Content\Seo\HreflangLoader::generateHreflangHome() was removed, use \Shopware\Core\Content\Seo\HreflangLoader::load() with route = 'frontend.home.page' instead.

Before

class CustomHrefLoader extends HreflangLoader
{
    public function someFunction(SalesChannelContext $salesChannelContext)
    {
        return $this->generateHreflangHome($salesChannelContext);
    }
}

After

class CustomHrefLoader extends HreflangLoader
{
    public function someFunction(SalesChannelContext $salesChannelContext)
    {
        return $this->load(
            new HreflangLoaderParameter('frontend.home.page', [], $salesChannelContext)
        );
    }
}
