[Android] Add test case for onReceivedErrorTest().

This patch is to add test case for onReceivedErrorTest().
Open some urls with error format, the resource client will receive
the related error. Verify the error information with the expected
result.
[Android] Embedding API v2

This commit added following APIs as Embedding API:
XWalkResourceClient.shouldOverrideURLLoading
XWalkUIClient.onUnhandledKeyEvent
XWalkUIClient.shouldOverrideKeyEvent
XWalkUIClient.onReceivedTitle
XWalkUIClient.onPageLoadStarted
XWalkUIClient.onPageLoadStopped

Some of those APIs were implemented inside xwalk core
internal previously. Now moving them to public Client
classes of XWalkView to expose in Embedding API.

Beside, remove the internal callbacks which are decided
not to expose in Embedding API and currently are dead code
or have empty implementation in core internal, including:
XWalkWebChromeClient.onReceivedTouchIconUrl
XWalkWebChromeClient.getDefaultVideoPoster
XWalkWebChromeClient.getVideoLoadingProgressView

TODO(wang16): Implement LoadStatus for XWalkUIClient.onPageLoadStopped.
