A few $Id$ references remained after commit
3f66f6a5b3 or appeared in newly added files.
Remove the lines containing svn keywords except when it concerns
third-party files. In that case keep the line as-is or collapse it to the
keyword if it had been expanded to contain wx commit information (only
occurs with src/zlib/ChangeLog).
Split wxXmlResourceHandler into an ABC and the real implementation to allow
referencing the ABC in the core library itself but without pulling in all of
the XRC into it. This also allows defining XRC handlers, which only depend on
this ABC and not the xrc library, in other libraries, such as richtext, as
demonstrated by the now enabled wxRichTextXMLHandler.
Closes#10996.
