#50102 Task 1: Move apimachinery/pkg/watch.Until into client-go/tools/watch.UntilWithoutRetry

**What this PR does / why we need it**:
This is a split off from https://github.com/kubernetes/kubernetes/pull/50102 to go in smaller pieces.

Moves `apimachinery/pkg/watch.Until` into `client-go/tools/watch.UntilWithoutRetry` and adds context so it is cancelable.

**Release note**:
```release-note
NONE
```

**Dev release note**:
```dev-release-note
`apimachinery/pkg/watch.Until` has been moved to `client-go/tools/watch.UntilWithoutRetry`.
While switching please consider using the new `client-go/tools/watch.UntilWithSync` or `client-go/tools/watch.Until`.
```
