gyp: Remove dependency on the views_test_support target.

This target brings in many additional dependencies on small static
libraries and should be used only by tests, as the name says. Instead,
depend on the event target, since we just need some symbols from it to
get the xwalk binary to link.

BUG=XWALK-2571
gyp: Stop using Chromium's bundled freetype2.

Remove the |use_custom_freetype| variable from xwalk.gyp and use the
system's Freetype instead.

The use_custom_freetype code came in from content_shell's gyp code when
we started the project. It is only used there for DumpRenderTree,
requires additional code to be built and is not used by the Chromium
browser at all.

BUG=XWALK-2571
gyp: Add dependency on snapshot.gyp:snapshot after 8bc6219.

Commit 8bc6219 ("[Tizen][Linux] Support getting thumbnail for devtools")
adds a call to ui::GrabViewSnapshotAsync but did not add a dependency on
the ui gyp target that contains the implementation of that function.

This broke the build of xwalk_browsertest on Linux when building with
component=shared_library:

  obj/xwalk/libxwalk_runtime.a(obj/xwalk/runtime/browser/devtools/xwalk_runtime.xwalk_devtools_delegate.o):xwalk_devtools_delegate.cc:function xwalk::XWalkDevToolsDelegate::GetPageThumbnailData(GURL const&):
  error: undefined reference to 'ui::GrabViewSnapshotAsync(aura::Window*, gfx::Rect const&, scoped_refptr<base::TaskRunner>, base::Callback<void (scoped_refptr<base::RefCountedBytes>)> const&)'

Fix it by adding the missing dependency.
[Tizen] packaging: Use the system's YASM instead of Chromium's.

This allows us to get rid of yet another bundled dependency that takes
time to build.

The YASM version shipped by Tizen (1.2.0) is the same one bundled in
Chromium, and the additional patches the latter has are of no relevance
to Tizen.
