Remove "pkg/controller/volume/scheduling" dependency from "pkg/scheduler/framework/plugins"

All dependencies of VolumeBinding plugin from
"k8s.io/kubernetes/pkg/controller/volume/scheduling" package moved to
"k8s.io/kubernetes/pkg/scheduler/framework/plugins/volumebinding" package:

- whole file pkg/controller/volume/scheduling/scheduler_assume_cache.go
- whole file pkg/controller/volume/scheduling/scheduler_assume_cache_test.go
- whole file pkg/controller/volume/scheduling/scheduler_binder.go
- whole file pkg/controller/volume/scheduling/scheduler_binder_fake.go
- whole file pkg/controller/volume/scheduling/scheduler_binder_test.go

Package "k8s.io/kubernetes/pkg/controller/volume/scheduling/metrics" moved
to "k8s.io/kubernetes/pkg/scheduler/framework/plugins/volumebinding/metrics"
because it only used in VolumeBinding plugin and (e2e) tests.

More described in issue #89930 and PR #102953.
