[Tizen IVI] Support landscape window orientation by default

Before the change 'NativeAppWindowTizen' hardcoded portrait
orientation to be the default one, however (unlike the mobile
devices) the default window orientation on IVI devices is
landscape. Thus the wrong window transformation was applied
causing bugs, e.g. XWALK-1313.

This patch adds support (not complete yet, but enough for most
of the applications) for the default landscape window orientation.

[Tizen][Runtime] Add support for 'hwkey' in Tizen widget configuration.

Tizen WRT Core Spec shows that when hardware key(‘back’, ‘menu’) is
pressed, WRT MUST send the “tizenhwkey” custom event to the Web
Application if the <tizen::setting hwkey=”disable”/> element is not
specified. Therefore, app developer can add customized behavior for
this.

Spec:
https://source.tizen.org/sites/default/files/page/tizen-2.2-wrt-core-spec.pdf
(item 0470)

This implementation will fetch event from OzoneMessagePump, if it is a
key event, and at the same time the 'hwkey' flag is not disabled in
widget configuration, browser process will send the event to render process,
so that RP can handle the hardware key event.

[Android] Catch missing libxwalkcore.so in make_apk.py

When Crosswalk is built as a shared component, libxwalcore gets a
.cr.so suffix, and make_apk silently bails, not finding it. This patch
checks for the existance of libxwalkcore.so, and prints an
understandable error when it is not there.
