Confilcts not resolved, except removal of the files removed
by the original commit.

* resolved conflicts and build issues after cherry-pick

* cherry-picked: fix: add method allowing to disable headless mode in native widget

* fix: displaying select popup in window created as fullscreen window

`constrainFrameRect:toScreen:` is not being call for windows created
with `fullscreen: true` therefore `headless` mode was not being removed
and `RenderWidgetHostNSViewBridge::DisplayPopupMenu` ignored displaying
popup.

Issue could be fixed by placing additional removal of `headless` mode
in the `toggleFullScreen:`, but `orderWindow:relativeTo:` is called
both for a regular and a fullscreen window, therefore there will be
a single place fixing both cases.

Because `electron::NativeWindowMac` lifetime may be shorter than
`ElectronNSWindow` on which macOS may execute `orderWindow:relativeTo:`
we need to clear `shell_` when `NativeWindow` is being closed.

Fixes #43010.

* fix: Content visibility when using `vibrancy`

We need to put `NSVisualEffectView` before `ViewsCompositorSuperview`
otherwise when using `vibrancy` in `BrowserWindow` `NSVisualEffectView`
will hide content displayed by the compositor.

Fixes #43003
Fixes #42336

In fact main issues reported in these tickets were not present after
cherry-picking original refactor switching to `views::WebView`, so
text could be selected and click event was properly generated. However
both issues testcases were using `vibrancy` and actual content was
invisible, because it was covered by the `NSVisualEffectView`.

* fix: EXCEPTION_ACCESS_VIOLATION crash on BrowserWindow.destroy()

Restored postponed deletion of the `NativeWindow`.

Restoration caused `DCHECK(new_parent_ui_layer->GetCompositor());` failure
in `BrowserCompositorMac::SetParentUiLayer` after the spec test:
`chrome extensions chrome.webRequest does not take precedence over Electron webRequest - http`
with stack:

```
This was probably the reason of removing `NativeWindow` immediately
in order to cleanup `views_host_` in `WebContentsViewMac` to prevent
using layer without compositor in `WebContentsViewMac::CreateViewForWidget`.

`[ElectronNSWindowDelegate windowWillClose:]` is deleting window host
and the compositor used by the `NativeWindow` therefore detach `NativeWindow`
contents from parent. This will clear `views_host_` and prevent failing
mentioned `DCHECK`.

Fixes #42975

* chore: Applied review suggestions

* refactor: directly cleanup shell
