[WK2][EFL] Encapsulate view states set-up within WebView

[Mikhail Pozdnyakov]

SSIA. Outcome:
1) Reduces usage of EwkView inside WebView class.
2) Reduces direct usage of WebPageProxy inside EwkView class.

LGTM, but are you sure the initial state is correct? any way to test it? Focus issues are hard to debug, so we better be certain

Initial states are set by evas callbacks while evas object creation, so the values will be certain anyway. However think, both isFocused and isVisible are better to be set to 'false' initially indeed.

Not a fan of "flag" for the argument name.

Ditto.

SetIsVisible maybe?

setFocused(false) call viewStateDidChange(WebPageProxy::ViewIsFocused)???

You duplicate states between WebPageProxy and WebView. This is a really bad idea.

Why don't you get rid of those APIs?

agree, SetIsVisible is better.

right, this code is in page proxy is invoked:

    if (flags & ViewIsFocused)     m_process->send(Messages::WebPage::SetFocused(m_pageClient->isViewFocused()), m_pageID);

so it just makes page proxy to query state from page client (web view itself).

there is no duplication, as page client is supposed to hold the state.

mm.. isViewVisible and isViewFocused are mandatory things to have for page client.
