DevTools: Make Android tabs unloaded from memory accessible via remote debugging protocol (3/3)

Step 3 out of 3:
- Implemented GetTitle, GetURL and RestoreIfNeeded in TabAndroid.h/.cc and TabBase.java
- Removed tab id parameter from TabBase#nativeInitWebContents
- Introduced a new DevToolsTarget implementation for an unloaded tab (relying on the new TabAndroid methods)
- Changed DevToolsServerDelegate to enumerate all tabs (including unloaded)
- Cleaned up after Step 1: 
  -- Made the new methods in TabModel pure
  -- Removed the bridge method TabAndroid::InitWebContents with the old signature.
  -- Removed TabAndroid::android_id()
