component-helpers dra: add AssumeCache

This is identical to the proposal from
kubernetes#112202. In contrast to the
AssumeCache in the volume binding scheduler plugin, this version of the code
does not make assumptions about the content of the ResourceVersion fields,
i.e. it does no "is newer than" comparison. Therefore objects might go back in
time under some circumstances.

This was seen as insufficient for inclusion in client-go, but for DRA its
better than not having the AssumeCache, so the code gets included here for use
in that controller.
