Surfaceflinger: Add transform info into dumpsys 

The minor dumpsys SurfaceFlinger enhancement explicitly exposes the
transform info of active buffers and HWC layers. It helps developers
understand more about when and why HWC layers are rotated.

Bug: b/80267683
Test: Keep dumpsys SurfaceFlinger during monkey test
