Whatever vmNetworkingType setting under ControlPlane in install-config, "Accelerated networking" on master instances are always disabled.

In install-config.yaml, set controlPlane.platform.azure.vmNetworkingType to 'Accelerated' or without such setting on controlPlane
=======================
controlPlane:
  architecture: amd64
  hyperthreading: Enabled
  name: master
  platform:
    azure:
      vmNetworkingType: 'Accelerated'
 
create cluster, and checked "Accelerated networking" on master instances, all are disabled.
$ az network nic show --name jima24c-tp7lp-master-0-nic -g jima24c-tp7lp-rg --query 'enableAcceleratedNetworking'
false

After creating manifests, checked capi manifests, acceleratedNetworking is set as false.
$ yq-go r 10_inframachine_jima24c-qglff-master-0.yaml 'spec.networkInterfaces'
- acceleratedNetworking: false

4.17.0-0.nightly-2024-06-23-145410

Always

1. Set vmNetworkingType to 'Accelerated' or without vmNetworkingType setting under controlPlane in install-config
2. Create cluster
3.

AcceleratedNetworking on all master instances are always disabled.

1. Without vmNetworkingType setting in install-config, AcceleratedNetworking on all master instances should be enabled by default, which keeps the same behavior as terraform based installation.
2. AcceleratedNetworking on all master instances should be consistent with setting in install-config.
