### Please describe the feature.

VirtualMachineScaleSetVMProfile missing Tags, despite ARM API supporting it

previous spec version added Tags to several related structs (VirtualMachineScaleSetNetworkConfiguration, VirtualMachineScaleSetPublicIPAddressConfiguration, etc.) but
not to VirtualMachineScaleSetVMProfile.

https://github.com/Azure/azure-sdk-for-go/issues/26608

Start with specification/compute/resource-manager/Microsoft.Compute/Compute/Compute/models.tsp at VirtualMachineScaleSetVMProfile, then compare the related structs that already received Tags in the previous spec version. Confirm the model definition represents the ARM-supported Tags field and verify the resulting specification changes are limited to the requested profile.
