Use fake provider for NetworkController unit tests (#18628)
* Use fake provider for NetworkController unit tests

In the unit tests for NetworkController, it's important to prevent
network requests from occurring. Currently we do that by using Nock.
However, the `core` version of NetworkController uses a fake provider
object. This is arguably a better approach for unit tests because it
prevents us from having to think about the behavior that a specific
middleware may have. For instance, the Infura middleware intercepts
`eth_chainId` to return a static result, and the block cache middleware
replaces the `latest` block tag with the latest block number, making an
extra call to `eth_blockNumber` in doing so. We have to account for
these kinds of behaviors when using Nock, but we do not need to do this
when using a fake provider.

This should make it easier to compare the difference between the unit
tests in this repo vs. in the `core` repo, which should ultimately help
us merge the two controllers together.

* Rename fake-provider-engine to fake-provider

* Rearrange imports

* Move fake-provider and fake-block-tracker into a directory and exclude it from coverage

* Make FakeBlockTracker inert, and fix JSDocs

* Remove generics from FakeProvider

* Call beforeCompleting (and beforeResolving) using async/await

* Fix signature of sendAsync; align other signatures within FakeProvider

* No need to check whether error is not a string

* Don't exclude the provider-api-tests directory from coverage

* Make sure to mock both net_version and eth_getBlockByNumber when testing network status

* Fix FakeProvider so that none of the methods have optional callbacks
