CA DRA: document which KEPs adding DRA features are supported by Cluster Autoscaler

Which component are you using?:

/area cluster-autoscaler /area core-autoscaler /wg device-management

Is your feature request designed to solve a problem? If so describe the problem this feature should solve.:

There's a ton of KEPs which add new features to DRA, on top of the main one which introduced DRA itself. Cluster Autoscaler has been integrated with some of them, targeting support for when the KEP reaches beta stage. But some KEPs have already slipped through the cracks and haven't been integrated into CA despite being beta.

Describe the solution you'd like.:

We should go through all the DRA KEPs, and add the status of their CA integration to the Cluster Autoscaler DRA documentation.

Additional context.:

This is a follow-up to introducing documentation for DRA support in Cluster Autoscaler (#7783).
