Init companion networks for all tasks

[tim-becker]

Currently the companionNetworks are only initialized during the deploy task, making them unusable in other tasks (such as test, run, console, etc.)

This PR moves the companion network initialization to the extendEnvironment call, so it applies to all tasks. This required making the initCompanionNetworks function synchronous, which is doable by using hardhat's LazyInitializationProviderAdapter to construct the companion network providers.

Unfortunately this new dependency in ethers throws errors with the current tsconfig.json of this project, so this also modifies the tsconfig.json to silence those errors. Otherwise, running tsc fails with

node_modules/hardhat/internal/core/providers/lazy-initialization.d.ts:26:51 - error TS2304: Cannot find name 'EventListener'.

26     addListener(event: string | symbol, listener: EventListener): this;
                                                     ~~~~~~~~~~~~~

For context, we need this because many of our scripts (which run via hardhat run) need to access contracts from multiple networks at once
