All file dialogs irrespective of source, platform and runtime will now be routed through CefFileDialogManager and trigger CefDialogHandler callbacks (see issue #3293). Adds Chrome runtime support for CefBrowserHost::RunFileDialog and CefDialogHandler callbacks. Adds Alloy runtime support for internal GTK file and print dialogs on Linux subject to the following limitations: 1. Internal GTK implementation: - Cannot be used with multi-threaded-message-loop because Chromium's internal GTK implementation is not thread-safe (does not use GDK threads). - Dialogs will not be modal to application windows when used with off-screen rendering due to lack of access to the client's top-level GtkWindow. 2. Cefclient CefDialogHandler implementation: - Cannot be used with Views because it requires a top-level GtkWindow. Due to the above limitations no dialog implementation is currently provided for Views + multi-threaded-message-loop on Linux. In cases where both implementations are supported the cefclient version is now behind an optional `--use-client-dialogs` command-line flag. Expressly forbids multiple simultaneous file dialogs with the internal platform implementation which uses modal dialogs. CefDialogHandler will still be notified and can optionally handle each request without a modal dialog (see issue #3154). Removes some RunFileDialog parameters that are not supported by the Chrome file dialog implementation (selected_accept_filter parameter, cef_file_dialog_mode_t overwrite/read-only flags).
