  [NFC][regalloc] Move ExtraRegInfo and related to LiveRangeStageManager

This would allow sharing the LiveRangeStageManager between different
RegAllocEvictionAdvisors. One scenario is for ML training, where we want
to capture what the default advisor would do, for bootstrapping (speeds
up training).
