`cosmossdk.io/core/appmodule.AppModule` API.

### AppModule Interface

Remove `Querier`, `Route` and `LegacyQuerier` from the app module interface. This removes and fully deprecates all legacy queriers. All modules no longer support the REST API previously known as the LCD, and the `sdk.Msg#Route` method won't be used anymore.
Support for the `AppModule` `Querier`, `Route` and `LegacyQuerier` methods has been entirely removed from the `AppModule`
interface. This removes and fully deprecates all legacy queriers. All modules no longer support the REST API previously
known as the LCD, and the `sdk.Msg#Route` method won't be used anymore.

Most other existing `AppModule` methods have been moved to extension interfaces in preparation for the migration
to the `cosmossdk.io/core/appmodule` API in the next release. Most `AppModule` implementations should not be broken
by this change.

The `ProvideModule` function should return an instance of `cosmossdk.io/core/appmodule.AppModule` which implements
one or more app module extension interfaces for initializing the module.

Following is the complete app wiring configuration for `group`:

We can remove AppModuleWrapper in runtime/wrappers.go, right?

TBH I would even remove WrapAppModuleBasic and all ProvideModuleBasics. Does depinject need the AppModuleBasics? Maybe only provide the appmodule.AppModules?

I removed AppModuleWrapper. I'll look into removing WrapAppModuleBasic. It's needed for codec instantiation, but maybe I can find a workaround.

I removed WrapModuleBasic. A bunch of boilerplate gone now. Should I go ahead and make the rest of AppModuleBasic extension interfaces? In particular HasInterfaces and HasAmino?

Yes, I think that's a good idea. Totally fine to do in a follow-up too, as this already has approvals. It's not breaking anyways, right?
