Expand jank classification

This change expands the jank classification to include new cases like
BufferStuffing and SurfaceFlingerScheduling while also updating the jank
classification logic to be more accurate.

This change also refactors SurfaceFrame by removing the abstraction
class for SurfaceFrame since its now being polled by the layers as well.

Bug: 169890654
Test: libsurfaceflinger_unittest
