[Why] Current recout calculation has a few assumptions and implementation for MPO + ODM combine calculation is very specific. The equation has too many cases without enough comments to document the detail. [How] The change remove the following assumptions: 1. When MPO is enabled, we only allow ODM Combine 2:1 2. ODM Combine always has even segment width. 3. Secondary MPO plane's pipe_ctx copies pre_odm_pipe from its top pipe. The change applies a generic formula with more details in comment to document this solution so it is eaiser to learn and debug later. Reviewed-by:

[Description] - Prevent ODM pipe connections between pipes that are not part of the same plane when adding a plane to context - Re-attach child pipes of ODM slice about to be disconnected to prevent any lost pipes with invalid tops/bottoms - We cannot split if head_pipe is not in ODM. Preventing this avoids creating an invalid context with an invalid pipe. Reviewed-by:

MES can concurrently schedule queues on the device that require exclusive device access if marked exclusively_scheduled without the requirement of GWS. Similar to the F32 HWS, MES will manage quality of service for these queues. Use this for cooperative groups since cooperative groups are device occupancy limited. Since some GFX11 devices can only be debugged with partial CUs, do not allow the debugging of cooperative groups on these devices as the CU occupancy limit will change on attach. In addition, zero initialize the MES add queue submission vector for MES initialization tests as we do not want these to be cooperative dispatches. Signed-off-by:
