Fix HOLD option not displayed in voice calls in CDMA + GSM.
Add hold button for all phone types and rely on SUPPORT_HOLD capability to show it.
The issue is that if GSM call is made on devices with CDMA + GSM sim, the default phone type is CDMA so the hold button is not available. This change is a workaround that adding hold button to CDMA button chooser so button choose of all phone type has hold button available and it's totally controlled by telecom's CAPABILITY_SUPPORT_HOLD and CAPABILITY_HOLD. It shouldn't affect CDMA call.
Idealy we should use correct phone type but unfortunately it's not well supported on pre-O device.
