Ignore SIM removed event when the system is shutting down

When the SIM is removed, the VVM account will be deactivated to protect user data. When the system is shutting down, the modem shutdown process will be interpreted as SIM removal and the event will be sent. This causes VVM to return to "not activated" state every time the phone is rebooted. If the phone is booted without signal or in airplane mode, the VVM tab will be missing since activation is not attempted without signal.

In this CL, BOOT_COMPLETED and ACTION_SHUTDOWN will be used to store the "shutting down" state in a shared preference. If the SIM is removed between ACTION_SHUTDOWN and BOOT_COMPLETED, it will be ignored.

SIM removal in FBE is already ignored. SIM removal in power off state is never handled.

If the broadcasts are missed (which is improbable), removing the SIM will not remove the VVM tab, until removing it again after the next boot.
