[ion] 25855: - Implement KdpGetStateChange. - Implement DbgKdContinueApi and DbgKdContinueApi2 cases. - Remove several while (TRUE); s which started being hit since our code is working fine. - WinDBG gets notifications for all the drivers/symbols being loaded and ROS now boots to bootvid logo, but we don't yet break-in.

Log:
- Implement KdpGetStateChange.
- Implement DbgKdContinueApi and DbgKdContinueApi2 cases.
- Remove several while (TRUE);s which started being hit since our code is working fine.
- WinDBG gets notifications for all the drivers/symbols being loaded and ROS now boots to
bootvid logo, but we don't yet break-in.
