[M67 Dev][WRT][EWK] Deprecate ewk_send_widget_info and add ewk_context_tizen_app_id_set

Original patch: http://165.213.202.130/gerrit/#/c/98860/
Original author: Marcin Niesluchowski <m.niesluchow@samsung.com>

ewk_context_tizen_app_id_set() does the same as ewk_send_widget_info()
but with removal of unnecessary parameters, which are not used in
plugins. Also name has been changed due its inconsistency with
implementation and usage. ewk_send_widget_info() was marked as
deprecated. Fix
utc_blink_ewk_context_new_with_injected_bundle_path_func.POS_TEST1
failing due to ewk_send_widget_info() api called after loading url.
Now ewk_context_tizen_app_id_set() is called before loading url
instead.

To complete api change following steps should be taken:
1) After this commit is merged all plugin libraries should add [1]
and [2] api and remove [3]. [1] api should return current plugin
verison - 1. [2] should act the same as [3] api.
ewk_context_tizen_app_id_set should be used instead of
ewk_send_widget_info.
2) After that ewk_send_widget_info deprecated api should be removed
in different commit.

For proper usage see following test file:
ewk/unittest/resources/ewk_context/injected_bundle/chromium/bundle_sample.cc

[1] unsigned int DynamicPluginVersion();

[2] void DynamicPluginStartSession(const char* tizen_app_id,
                                   v8::Handle<v8::Context> context,
                                   int routing_handle,
                                   const char* base_url);

[3] void DynamicPluginStartSession(const char* tizen_id,
                                   v8::Handle<v8::Context> context,
                                   int routing_handle,
                                   double scale,
                                   const char* encoded_bundle,
                                   const char* theme,
                                   const char* base_url);
