[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.
[Android] Disable PauseResumeTest for runtime client

As the XWalkView now doesn't relies on embedders to
call onHide/Show and pause/ResumeTimer when Activity
state changes.
The onPause/onResume callback in XWalkRuntimeClient is
now empty. We need to find another solution to
actually pause/resume the Activity to test the case.

Disable the test before that.

[Android] Naming refine for packaging tool

First, the new w3c manifest spec requires accepting any string to be application name.
However in previous make_apk process, they were treated as invalid input.
Second, in the past time, this part of logic is always buggy and
each sub process is validating and modifying the name passed by.
It's a good time to consolidate all these codes and validate the name at beginning,
to produce all necessary strings (transferred from the input name)
for all purposes during the make apk process.
