Improved {% include %} implementation

Merged BaseIncludeNode, ConstantIncludeNode and Include node.

This avoids raising TemplateDoesNotExist at parsing time, allows recursion
when passing a literal template name, and should make TEMPLATE_DEBUG behavior
consistant.

Thanks loic84 for help with the tests.

Fixed #3544, fixed #12064, fixed #16147
