Improve customer selection with website scope

[kpitn]

With new version, module fetch all websites in gdpr_erase_entity_scheduler cron

  foreach ($this->storeManager->getWebsites() as $website) {
            if ($this->config->isErasureEnabled($website->getId())) {
                try {
                    $this->eraseEntityScheduler->schedule($this->entityTypeList->getEntityTypes(), $website);
                } catch (Exception $e) {
                    $this->logger->error($e->getMessage(), ['exception' => $e]);
                }
            }
        }

we can improve customer query by scoping with website_id

We can use the addFieldToFilter method available on collection here:
$collection->addFieldToFilter('website_id', $website->getId());

We use 'where' at line .46 because it's a complex condition, and we use 'joinLeft' because the default 'join' method available on collection force inner joins.
