Move eSIM factory reset implementation to RecoverySystem

This CL reverts the implementation of eSIM factory reset in
MasterClearReceiver and uses RecoverySystem#rebootWipeUserData to erase
eSIM data. Besides this, when the eSIM data isn't erased, we should call
EuiccManager#retainSubscriptionsForFactoryReset to let the fastboot know
that.
