[Android] Pre-initialize the CPU information for ARM platform

On ARM platform, the cpu information is fetched from /proc/cpuinfo
which requires the right to allow accessing IO. Howerver, in Crosswalk,
the IO/IPC thread is not allowed to IO access unless
ThreadRestriction::SetIOAllowed(true) is called explicitly.

This fix is to pre-initialize the CPU info in advance to avoid thread
restrictions on reading /proc/cpuinfo.

[Runtime][Tizen] Support to set app window view mode by configure
config.xml

We support configuring application window display mode by 'display'
field in manifest.json for XPK packages. While this way is not enabled
for widget format packages.

The Widget Spec tells that 'viewmodes' attribute denotes the author's
preferred view mode.

This CL enables the 'viewmodes' attribute check for Widget applications.
