Remove DiscoveredPathContainerPage

The class DiscoveredPathContainerPage used a number of APIs in
the Eclipse Platform
[removed](eclipse-platform/eclipse.platform.ui#1563) in
[Eclipse 4.31 release](https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/blob/81e406456ffae2f82fe0bb244adfdc4121c9e463/eclipse.platform.common/bundles/org.eclipse.platform.doc.isv/porting/removals.html#L595).
This class, while API, has not be used, nor usable since the CDT 4
release as it was only for CDT 3.x style projects.
The class had been deprecated since 2010.

To mitigate against the possibility that someone may have a dependency
on this old class the minor version has been bumped so that version
range can have `,8.3)` as their upper version.

Fixes eclipse-cdt#700
