qdoc: Drop remnants of unimplemented feature \generate examplefiles

Previously QDoc provided a \generatelist example[files|images] <regexp>
feature to list example files matching a specific regular expression,
but it was left non-functional after changes to example documentation
generation.

Remove remnants of the related code paths and documentation.

-    \section2 \c {examplefiles [regular_expression]}
-
-    The \c examplefiles argument lists the files that are part of
-    an example project. The optional second argument is a regular
-    expression; if provided, only the files whose path matches with
-    the regular expression are listed.

-    The \c examplefiles argument can be only used within example
-    documentation (see \l {example-command}{\\example}), and is
-    typically used together with the \l {noautolist-command}{\\noautolist}
-    command.

-    The \c exampleimages argument lists the images that are part of
