Implement support for overriding content mime type.

This adds EFL port implementation of ResourceDispatcherHostDelegate's
ShouldOverrideMimeType function. The code exposes this interface via EWK
context object. Due to the fact chromium resource dispatcher host
delegate is a singleton object the interface is exposed as a static
function in WebContext.
