CRAS: cras_server_metrics - Fix some bugs about device type

Fix some mistakes about device type.
1. Replace CRAS_METRICS_DEVICE_NORMAL(ABNORMAL)_SILENT_HOTWORD with
CRAS_METRICS_DEVICE_SILENT_HOTWORD because the silent hotword should
always be in the normal situation.
2. Typo 'slient' -> 'silent'
3. Let CRAS_CLIENT_TYPE_SERVER_STREAM be converted to string.

BUG=b:141286272
TEST=These logs can be recorded correctly on eve.
