fix: incorrect size of windows on differently scaled monitors

[deepak1556]

Description of Change

This reverts #19928 , we need the SetWindowPlacement hack for the scaling to work correctly and the problem this PR was trying to address #19423 can be fixed my not resetting the size of last_normal_placement_bounds_ a1562bd before adjusting the window placement as it had essentially null'd the right and bottom coordinates.

Fixes #20683
Fixes #20527
