[Android] Fix that make_apk_test fails when out/ has both ARM and x86 builds

Both testCustomizeFile and testEmptyMode fail when out happens to have
both an ARM and an x86 build: in this case, the ARM native libraries will be around
and make_apk.py will generate both ARM and x86 APKs,
making the self.assertFalse(os.path.isfile('Example_1.0.0_arm.apk')) call fail.

[application] application installation should not cause termination of all the running apps

Before the change installation of any application, having the main document,
caused xwalk process termination (and hence termination of all the running
applications).
This patch fixes it so that only the installation-related application is
terminated and the rest applications remain being active.

[Android] Try to match cpu arch after loading xwalk core

It's extremely slow to load ARM binaries on ia devices.
And it hurts user experience. Add a method in libxwalkcore.so
to tell XWalkViewDelegate whether the binary is built for IA.

The exception of CPU architecture mismatch will be handled
by XWalkView instead of dispatch to runtime level or embedders.

A AlertDialog will be shown to notify user what's wrong and
suggest them report feedback to application developers or
rate and comment the application on PlayStore.

[Android] Allow XWalkUIClient to overwrite openFileChooser

Previous, select file is handled within xwalk_web_contents_delegate
and the openFileChooser API in XWalkUIClient is not working.
"openFileChooser" is used in android.webkit.WebChromeClient, which
is adopted by many current webview users (e.g. Cordova).

In this commit, it dispatches the request to XWalkUIClient which is
empty implementation. If the derives override the implementation,
it can invoke the callback somewhere to provide the chosen file.
Otherwise, it will fallback to internal solution using
RuntimeFileSelectHelper::RunFileChooser.

[Tizen] Add application hide support

Tizen Application.hide() API need this support to hide current application.

When Hide method is called on the runnning application object, all windows
owned by this application will be hide.
[Android] Launch Screen full spec implementation

As the spec defined, the launch screen contains 3 layers:
1. background color
2. background image
3. foreground image
It's impossible to show all these layers together when an icon is tapped, because
of the limitation of 'Android drawable' mechanism.
The actual working flow is as below:
 - Display the first 2 background layers.
 - Display the 3rd foreground image layer with a Dialog.

Below is the description for the implementation in general:
Build script:
1. Parse manifest.json and customize launch screen.
2. Generate drawable:launchscreen_bg.xml depends on the configuration defined.
3. Copy background and foreground images to res folders.
Runtime:
1. Create a new layout to display 9-piece format foreground image.
2. Parse image-border from manifest.json, and customize the layout.
3. Display the 3 layers in a Dialog.

TODO:
One feature missed in this patch:
'ready_when' = 'user-interactive'
