tests/kms_plane_scaling: test for multi pipe with scaling, v3.

Add a subtest to display primary and overlay planes on two
connected pipes and runs scaling test on both pipes

Changes since v1:
- Commit first before trying any scaling. (Maarten)
- Use the same logic as kms_cursor_legacy to find a pipe and output. (Maarten)
- Rework test to work with how cleanup is handled. (Maarten)
Changes since v2:
- Use get_num_scalers() to only use 2 scalers if available. (Maarten)
