fix: Update widget visibility in NativeWindowMac::ShowInactive (#45502)

Browse source 
When using `views::WebView` on macOS `NativeWidgetMacNSWindowHost`
contains a layer and compositor responsible for drawing web contents.
To trigger drawing `NativeWidgetMacNSWindowHost::OnVisibilityChanged`
needs to be called and `[NSWindow orderFrontRegardless]` does not trigger
`[NSWindow orderWindow:relativeTo:]` which can change
`NativeWidgetMacNSWindowHost` visiblity with stack:
```
views::NativeWidgetMacNSWindowHost::OnVisibilityChanged(bool)
remote_cocoa::NativeWidgetNSWindowBridge::OnVisibilityChanged()
-[ViewsNSWindowDelegate onWindowOrderChanged:]
-[NativeWidgetMacNSWindow orderWindow:relativeTo:]
```
`views::Widget` has method for showing inactive window:
`views::Widget::ShowInactive` which triggers
`NativeWidgetMacNSWindowHost::OnVisibilityChanged` with stack:
```
views::NativeWidgetMacNSWindowHost::OnVisibilityChanged(bool)
remote_cocoa::NativeWidgetNSWindowBridge::SetVisibilityState(remote_cocoa::mojom::WindowVisibilityState)
views::NativeWidgetMacNSWindowHost::SetVisibilityState(remote_cocoa::mojom::WindowVisibilityState)
views::NativeWidgetMac::Show(ui::mojom::WindowShowState, gfx::Rect const&)
views::Widget::ShowInactive() + 168
```
However this call seems to be insufficient to bring window to front,
therefore `[NSWindow orderFrontRegardless]` still needs to be called.
Calling `views::Widget::ShowInactive` ensures that all logic related to
showing Chromium widget will be properly executed, but onfortunately it
does not call `[NSWindow orderWindow:relativeTo:]` which is used to
disabling headless mode by the `ElectronNSWindow`, therefore we need to
trigger it manually through exposed `[ElectronNSWindow disableHeadlessMode]`.

Fixes: #45415
