refactor: use mojo for electron internal IPC (#17406)
* refactor: use mojo for electron internal IPC

* add sender_id, drop MessageSync

* remove usages of AtomFrameMsg_Message

* iwyu

* first draft of renderer->browser direction

* refactor to reuse a single ipc interface

* implement TakeHeapSnapshot through mojo

* the rest of the owl^WtakeHeapSnapshot mojofication

* remove no-op overrides in AtomRendererClient

* delete renderer-side ElectronApiServiceImpl when its pipe is destroyed

* looks like we don't need to overlay the renderer manifest after all

* don't try to send 2 replies to a sync rpc

* undo changes to manifests.cc

* unify sandboxed + unsandboxed ipc events

* lint

* register ElectronBrowser mojo service on devtools WebContents

* fix takeHeapSnapshopt failure paths

* {electron_api => atom}::mojom

* add send_to_all to ElectronRenderer::Message

* keep interface alive until callback is called

* review comments

* use GetContext from RendererClientBase

* robustify a test that uses window.open

* MessageSync posts a task to put sync messages in the same queue as async ones

* add v8::MicrotasksScope and node::CallbackScope

* iwyu

* use weakptr to api::WebContents instead of Unretained

* make MessageSync an asynchronous message & use non-associated interface

* iwyu + comments

* remove unused WeakPtrFactory

* inline OnRendererMessage[Sync]

* cleanups & comments

* use helper methods instead of inline lambdas

* remove unneeded async in test

* add mojo to manifests deps

* add gn check for //electron/manifests and mojo

* don't register renderer side service until preload has been run

* update gn check targets list

* move interface registration back to RenderFrameCreated
