Configure some batch delegation options

[enisdenjo]

Ref GW-451

To change the max batch size from Infinity to 10, for example, do this:

import { defineConfig } from '@graphql-hive/gateway';

export const gatewayConfig = defineConfig({
  __experimental__batchDelegateOptions: {
    maxBatchSize: 10,
  },
});

Note that there are many more batch delegation (GraphQL DataLoader) options to choose from, but we want to keep user changes to a minimum to the internal workings.

Also, remove memlabs from an internal package (an overlooked leftover of #1372).

Pull Request Overview

This PR configures batch delegation options for GraphQL DataLoader and renames an experimental configuration option. The changes allow users to configure batch delegation behavior (like maxBatchSize) while keeping the API minimal, and correct a naming inconsistency in the batch execution configuration.

• Rename __experimental__batchDelegation to __experimental__batchExecution for clarity
• Add new __experimental__batchDelegateOptions configuration to control batch delegation behavior
• Remove unused memlab dependency from internal perf package
