Cluster autoscaler more AWS DescribeLaunchTemplateVersions due to PR-6245

[linhua11]

Which component are you using?: cluster-autoscaler

What version of the component are you using?: 1.29.2 and 1.29.4

Component version:

What k8s version are you using (kubectl version)?: 1.29

kubectl version Output

$ kubectl version

What environment is this in?: AWS

What did you expect to happen?: No increased AWS API call due to rate limit issue

What happened instead?: Due to PR-6245, even if we don't use MixedInstancesPolicy.instanceRequirements since we use balacing-label and having active nodes. It still calls DescribeLaunchTemplateVersions which pushes the CA to have some rate limiting issue. And there is no way to disable this feature

How to reproduce it (as minimally and precisely as possible):
Just start a CA with balancing labels like
- --balancing-label=xxxxx
- --expander=least-waste
- --aws-use-static-instance-list=true
Compare the number of aws api calls between version 1.27.6 and 1.27.7, you will find increased API calls

Anything else we need to know?:
