telemetry(common): add new value to saveType metric #939

## Problem
`saveType` metric (used for threat composer and step functions
integrations) does not have an value for auto-sync event (i.e. when the
content from webview is auto-synced with local file)

## Solution
Add `AUTO_SYNC` value to the metric
