Introduce AbstractInlinedAnnotation#getMinings() to expose ICodeMining

list

Adds a new public API method `getMinings()` to
`AbstractInlinedAnnotation` that provides read-only access to the list
of `ICodeMining` instances associated with an inlined annotation.

This API is needed to implement the unified diff feature via
eclipse-platform/eclipse.platform#2560
