Move frame tree back into core

Project Member Reported by dcheng@chromium.org, May 28 2017 
It's a bit awkward that it's maintained in web right now: it means we need extra plumbing for a core frame to figure out its parent frame, etc, we need to expose the frame tree to the embedder in a very direct way, maintaining openers needs to be at the web layer, along with the awkward tracing involved (since WebFrame itself inherit from GarbageCollected).

We can simplify this by:
1. Removing AddChild()/RemoveChild() etc from the public API and exposing a WebLocalFrame::CreateChild to match WebRemoteFrame::CreateLocalChild and WebRemoteFrame::CreateRemoteChild.

2. Change frame detach to automatically remove the frame from the frame tree rather than relying on the embedder to do it in WebFrameClient::FrameDetached().

3. Construct blink::Frame at the same time as blink::WebFrame. This will require changing the way we set the main frame: instead of doing it in the Frame constructor, we can have WebView::SetMainFrame() set the main frame, while the various Web*Frame::Create*Child methods will attach the frame to the frame owner.

4. Move the frame tree itself into blink::Frame and remove the plumbing in the Web layer.

The following revision refers to this bug:
  https://chromium.googlesource.com/chromium/src.git/+/01f99abb0f0a8a68fcf01527068d481c16bd70c0

commit 01f99abb0f0a8a68fcf01527068d481c16bd70c0
Author: Daniel Cheng <dcheng@chromium.org>
Date: Mon May 29 21:16:26 2017

Remove frame tree management functions from WebFrame public API.

This was originally done in Blink: however, since the frame tree wasn't
updated until WebFrameClient::CreateChildFrame returned, RenderFrameImpl
initialization was tricky since code that just used the WebLocalFrame
directly wouldn't know if the frame was a child frame or not without
plumbing around extra arguments.

To fix this, Blink exposed functions to manage the frame tree to the
embedder. However, this started resulting in a lot of boilerplate code
copied between various WebFrameClient implementations--as well as the
possibility that the embedder could unsync the frame tree from Blink's
internal state.

Make WebLocalFrame 1:1 with TestWebFrameClient

Several helpers are added to make it easier to write
test code:
- TestWebFrameClient can optionally delete itself on
  frame detach.
- Adds helpers for creating new local frames, so test
  code doesn't have to specify uninteresting arguments.
- Adds LocalMainFrame() and RemoteMainFrame() helpers
  to WebViewHelper to make it easier to get the main
  frame in the appropriate form.

Followup CLs will make remote frames use a similar
pattern, with the eventual goal of having methods to
create main frames and addressing some longstanding
TODOs.

Improve test helpers for remote frames.

The test framework now automatically creates and manages
the lifetime of WebRemoteFrameClient and WebWidgetClient
internally when no subclassing is required. Test helpers
for initializing a remote main frame have also been
added.

FrameTestHelpers: eliminate explicit clients that are redundant

There's usually no need to explicitly create a TestWebFrameClient,
TestWebRemoteFrameClient, TestWebWidgetClient, or TestWebViewClient: the
test framework can handle creation of these internally. It's only when a
test needs to extend the behavior that it's useful to create an explicit
client; otherwise, it just makes the test more complex for no benefit..

Add WebFrameClient::BindToFrame() to fix RenderFrameImpl association.

WebLocalFrame initialization fires a few WebFrameclient callbacks before
WebLocalFrame creation has returned control to the caller. In that case,
the caller's WebFrameClient won't know its associated WebFrameClient
yet.

BindToFrame() is called after WebLocalFrame is constructed, but before
any other WebFrameClient callbacks are invoked, guaranteeing that the
two objects will be associated before any other callbacks.

Move WebViewFrameWidget to the Oilpan heap.

A followup patch will move lifetime management of WebFrame /
WebFrameWidget into Blink. Using a common cleanup path will make things
simpler.

Add factory creation methods for creating local and remote main frames.

- Creating a main frame no longer requires passing a pointless tree
  scope type, since the main frame is never in the shadow tree.
- Consistently set name / sandbox flags in Blink via CreateMainFrame().
  This makes the browser and renderer-driven main frame creation paths
  more similar.
- Remove WebLocalFrame::Create() as it no longer needs to be exposed to
  the embedder.
