Update CARM feature gates in Helm values template

This patchh updates the feature gates configuration in the Helm values
template:

- Removes the `CARMv2` feature gate
- Adds two new feature gates:
  - `ServiceLevelCARM`: Enables Service level granularity for CARM
  - `TeamLevelCARM`: Enables Team level granularity for CARM

Both new feature gates are set to `false` by default.

See aws-controllers-k8s/community#2031 for more
information on these CARM granularity levels.
