Reviewed by Michael Catanzaro.

By default IndexedDB API is enabled. To change that we can use runtime flag: "enable-html5-database" or by calling "webkit_settings_set_enable_html5-database".

• Source/WebKit/UIProcess/API/glib/WebKitSettings.cpp: (webkit_settings_get_enable_html5_database): (webkit_settings_set_enable_html5_database):

Tested with COG on RPi: cog --enable-html5-database=0 https://www.igalia.com and try to call window.IDBCursor in web inspector. It is unknown type.
