[Android] Fix crash caused by calling pauseTimer twice in row

The timer is actually global in current implementation.
Use a static boolean to record the status to avoid duplicated
calling pauseTimer().

[Runtime] Support launch an url from launcher.

After commit 4f4eca4773e7e4a98dc0198fdca1bae1886c749e

We always compile a Shared Process Model binary for
tizen, and it always run as shared process model, so we cannot
launch a page with url like 'xwalk http://www.google.com'.

There is an easy way that we can support launch an url from
launcher, and create an temp app for url.

[Android][Extension] Move extension tests to core_internal.

ExtensionEcho(renamed as ExtensionEchoInternal) uses core_internal interface
XWalkExtensionAndroid, so this extension along with the test should move
from core into core_internal.

Same thing ExtensionBroadcast.
[Tizen][Runtime] Improve query running app.

Fix cannot query running for wgt app with tizen_app_id on tizen.
Fix core dumped when query running without app id.

Query running will return result code(0 for success and 1 for
fail), so that we can check the result code about the status of
the app.

[Android] React to activity state change within XWalkView

Previously, XWalkView relies on embedders to manage the
resource of XWalkView based on Activity lifecycle.

In this commit, implement XWalkView as ActivityStatusListener
and handle the lifecycle state change by itself.

[Tizen][Runtime] Fix bug: crash on installation of a wgt without application
element in config.xml

According to
https://source.tizen.org/sites/default/files/page/tizen-2.2-wrt-core-spec.pdf
<tizen:application / > MUST occurrence one time.

If application element is not found in manifest, the parser should
 stop and the installation will fail.
[Android]Fix Android build failure from scratch after b6623da.
This happens on the Android debug builds because of lack of the dependency on ui/compositor when building the source files splash_screen.h|.cc. Here is the error message:
    obj/xwalk/libxwalk_runtime.a(obj/xwalk/runtime/browser/ui/xwalk_runtime.splash_screen.o): in function vtable for xwalk::SplashScreen:splash_screen.cc(.data.rel.ro._ZTVN5xwalk12SplashScreenE+0x134): error: undefined reference to 'ui::ImplicitAnimationObserver::OnAttachedToSequence(ui::LayerAnimationSequence*)'

Since the splash_screen.h|.cc are tizen-specific, this fix is to rename the files by adding suffix "_tizen" so that they can excluded from Android builds. The class name is also modified to keep consistency, e.g change class SplashScreen to class SplashScreenTizen.
