drm/amd/display: Fix windowed MPO video with ODM combine for DCN32

Browse source

[Why]
In single display configuration, windowed MPO does not work
 with ODM combine.

[How]
For ODM + MPO window on one half of ODM, only 3 pipes should
 be allocated and scaling parameters adjusted to handle this case.
 Otherwise, we use 4 pipes.
Move copy_surface_update_to_plane() before dc_add_plane_to_context()
 so that it gets the updated rect information when setting up
 the pipes.
Add dc_check_boundary_crossing_for_windowed_mpo_with_odm() to force
 a full update when we cross a boundary requiring us to reconfigure
 the number of pipes between 3 and 4 pipes.
Set config.enable_windowed_mpo_odm to true when we have the
 debug.enable_single_display_2to1_odm_policy set to true.
Don't fail validating ODM with windowed MPO if
 config.enable_windowed_mpo_odm is true.
