In the `core` version of NetworkController, `removeNetworkConfiguration`
throws an error if the given network configuration ID doesn't match an
existing network configuration. This commits adds the same check for
consistency. It also makes some minor changes to the implementation and
tests for `removeNetworkConfiguration` for consistency as well.
The network controller method `setActiveNetwork` is now async, and the
asynchronous `_setProviderConfig` step is now awaited. The function
will not resolve until the network has finished switching.
This change affects the `eth_switchEthereumChain` and
`eth_addEthereumChain` middleware, and it affects any network switching
performed in our UI.

The network controller method `setProviderType` is now async, and the
async operation `_setProviderConfig` called at the end of the method is
now awaited.
Because the only async operation was the last step, this should have no
impact upon the flow of execution. The only functional change is that
now any callers have the option of waiting until the network switch
operation has completed.
One such change was made, in the `switch-ethereum-chain` middleware. As
a result, an error thrown while the network is switching will now
be thrown in this middleware and returned to the dapp as an internal
error.

* Consolidate network stores
The network controller used to have multiple different state stores,
which were composed together to form the main controller state store.
They have been consolidated into a single store. This required few
changes because most state access was already being done through the
composed store.

* Add JSDoc comment
Internal network controller methods and fields are now private fields,
using the JavaScript `#` syntax rather than the `private` TypeScript
keyword or a leading underscore.
The one reference to a private field was in the preferences controller
unit tests. Fortunately it was being used to create a test fixture that
was unused. The unnecessary test fixtures have been removed from that
test suite.
Fixes https://github.com/MetaMask/metamask-extension/issues/18588
The network controller internal method `_setProviderConfig` has been
made async, the async `_switchNetwork` operation is now `await`-ed.
Since the `_switchNetwork` call was the last operation, this has zero
functional impact.

* Remove the network controller `previousProviderStore`
The `previousProvider` network controller state has been replaced with
a private internal property. This was only used internally, it did not
need to be part of state.
This relates to https://github.com/MetaMask/metamask-extension/issues/18303
* Remove redundant tests
The network controller internal method `_switchNetwork` has been made
async, and the `lookupNetwork` call is now awaited. Because this method
is only used internally, and because the `await`-ed async operation was
the last operation in this function, this change has no functional
impact whatsoever.

This helps us more easily compare the unit tests for NetworkController
in this repo and the NetworkController in the `core` repo.

Converting this controller to TypeScript furthers the goal of getting
this whole codebase converted, of course, but it also helps in comparing
the differences between this version of the NetworkController and the
version in the `core` repo more easily, which will ultimately help us in
coalescing the two implementations.
