[Feature]: New-AzSqlDatabaseImport authenticate using an access token instead of username / password.

### Description of the new feature

Today, New-AzSqlDatabaseImport authenticate using username / password.

It would be nice to be able to authenticate via access token, using the following command where I've replaced
-AdministratorLogin $Credential.UserName -AdministratorLoginPassword $Credential.Password
with
-AccessToken = (Get-AzAccessToken -ResourceUrl https://database.windows.net).Token

$importRequest = New-AzSqlDatabaseImport `
-ResourceGroupName $SqlServer.ResourceGroupName -ServerName $SqlServer.ServerName `
-DatabaseName $DatabaseName `
-AccessToken = (Get-AzAccessToken -ResourceUrl https://database.windows.net).Token `
-Edition GeneralPurpose `
-StorageKeyType StorageAccessKey `
-StorageUri $storageURI `
-StorageKey $storageKey `
-ServiceObjectiveName GP_S_Gen5_4 `
-DatabaseMaxSizeBytes $DatabaseMaxSizeBytes
