[Feature]: Add AzureFilesIdentityBasedAuth ActiveDirectoryProperties

### Description of the new feature

Include AzureFilesIdentityBasedAuth AD Propertie as part of the data displayed by cmdlet Get-AzStorageFileServiceProperty to get the type of domain identity based enabled on the storage account AD, AADS or AAD Kerberos

### Proposed implementation details (optional)

Include AzureFilesIdentityBasedAuth ActiveDirectoryProperties as part of the data displayed by cmdlet Get-AzStorageFileServiceProperty

Currently, this is the only approach to pull that info from PS. However, it doesn't tell you what kind of domain authentication you are using AD, EntraDS or AAD Kerberos, output just give you details of the domain

# Get the target storage account
$storageaccount = Get-AzStorageAccount `
-ResourceGroupName "" `
-Name ""

# List the directory service of the selected service account
$storageAccount.AzureFilesIdentityBasedAuth.DirectoryServiceOptions

# List the directory domain information if the storage account has enabled AD DS authentication for file shares
$storageAccount.AzureFilesIdentityBasedAuth.ActiveDirectoryProperties
