Move FindFocusedEditableText from gtk* into vcl

Now that it will be used by four VCL plugins, move its code into
the common VCL library. The none-XAccessibility, none-UNO version
used on Windows needs much more work to function with various
widgets (including some API refactoring IMHO).
(see ImplHandleSalSurroundingTextRequest and friends).
