Enable autoscaling tests for CAPZ (Azure) provider

[iuriaranda]

Summary

• Remove AutoScalingSupported = false override from all three CAPZ test suites (standard, private, upgrade)
• Add missing scale_helloworld_values.yaml test data files for standard and upgrade suites
• The default NewTestConfigWithDefaults() already sets AutoScalingSupported: true

Test plan

• Verify CAPZ standard, private, and upgrade test suites compile
• Confirm autoscaling scale test runs successfully against a CAPZ cluster with cluster-autoscaler deployed

Oh No! 😱 At least one test suite has failed during the AfterSuite cleanup stage and might have left around some resources on the MC!

Be sure to check the full results in Tekton Dashboard to see which test suite has failed and then run the following on the associated MC to list all leftover resources:
