[Tizen] Get rid of the crosswalk-emulator-support package.

crosswalk-emulator-support was used during the Tizen 2.x times because the
Tizen emulator's GL implementation did not work as expected and we thus had
to fall back to libosmesa.

Now that Tizen 2.x is a thing of the past, we can get rid of it. If the
Tizen 3 emulator still has problems, we are now in the position to try to
fix it.
[Runtime] Add Widget Access Request Policy (WARP) parsing handler for
WGT package.

Add a WARP handler into the WGT package parser. The WARP spec reference
link is: http://www.w3.org/TR/widgets-access
[Runtime] Use Manifest::HasPath() method instead of the
Manifest::HasKey().

Since the Manifest::HasKey() method is looking for the key under current
ValueDirectory object, this is not compatible with WGT manifest file
structure, so change it to Manifest::HasPath().

Fix one coding style issue.

Bump Crosswalk to 34.0.1847.45

This includes build fixes deu to renamings in Chromium, as well as the
following squashed commits:

Author: Thiago Marcos P. Santos <thiago.santos@intel.com>:
- [SysApps] Fix component build
- [SysApps] Update StorageMonitor usage : Now we need
  to ::Create() the instance explicitly before using.

Author: Shiliu Wang <shiliu.wang@intel.com>:

  Upstream moves RegisterLibraryLoaderEntryHook from content

  Add the callback back to fix the issue.
