How to categorize this PR?

/area ops-productivity
/kind enhancement

What this PR does / why we need it:
Destroy gardener-resource-manager early in the shoot deletion flow.
In the hibernation flow the GRM is already scaled down to 0 replicas, so no changes needed there.

Which issue(s) this PR fixes:
Fixes #5464

Special notes for your reviewer:
@plkokanov I will be grateful if you include this in the v1.41 milestone.

Release note:

The `gardener-resource-manager` is now destroyed early in the deletion flow. In this way there will not be a failing deployment with PDB that prevents graceful termination of seed nodes.
