This PR makes `PlatformWasm` a `RemoteAwarePlatform` that can connect to a remote GDB platform server. `PlatformWasmRemoteGDBServer` inherits from `PlatformRemoteGDBServer`, with the only difference that it picks the correct Process plugin when launching and attaching. The approach is identical to the one taken by `PlatformAndroid`. The context is that we're working on a platform based approach for discovering and attaching Wasm processes running under JSC with the [newly added debugging support](https://github.com/WebKit/WebKit/pull/51462).
