[Android] Switch RenderView to RenderFrame for IoThreadClient impl

Since Chromium starts to support out-of-process iframe, RenderViewHost
is now replaced by RenderFrameHost, and in future it will be deprecated, as a
result, instead of watching a RenderView creation, we should watch a
RenderFrame creation to set the data for IoThreadClient impl. Reference
https://codereview.chromium.org/114573003 for more info.

In addition, we also enable 21 test cases for shouldInterceptRequest

BUG=https://crosswalk-project.org/jira/browse/XWALK-996
TEST=org.xwalk.core.xwview.test.XWalkClientShouldInterceptRequestTest
Fix build for Mac.

- Various clang erros.
- Fix the build of the sysapps unit tests grabbing dependencies not
needed (they will be included elsewhere) and guard the one needed
behind a conditional check of Aura (Mac doesn't use Aura).

[Android] Enable WebAudio on android x86 platform by default

In fact, functionality of WebAudio API was enabled on android x86 platform,
but it was disabled by default on android x86 chromium.

WebAudio is an important HTML5 API for Crosswalk, since some game engines
are using it, so we need to enable it by default.
